In order to reveal the influences of super-thick and hard strata on abutment pressure and the evolution law of energy distribution in stope, a typical mining area of Yangliu Coal Mine was taken as the research object, and the variation law of abutment pressure and energy evolution process were simulated by numerical simulation method. The results are concluded as follows. (1) When there are super-thick and hard strata in the overlying strata, the advance abutment pressure in the middle and both sides of the working face is increased by about 9% and 5% respectively compared with that without super-thick and hard strata. This shows that when there are super-thick and hard strata in the overlying strata, the middle and both sides of the stope are in a high stress state for a long time. When the stope is disturbed by external force, it is more likely to lead to the occurrence of dynamic disasters such as mine earthquake and rock burst. (2) When there are super-thick and hard strata in the overlying strata, the change curve of the advance abutment pressure of the stope shows a cliff-like decline after breaking. When there are no super-thick and hard strata in the overlying strata, the change curve of the advance abutment pressure of the stope is gentler than that of the former. (3) With the continuous advancement of the working face distance, the peak value of the abutment pressure of the free side is increased by 3.60 MPa and 3.39 MPa respectively compared with the peak value of the abutment pressure of the mining side when there are or are not super-thick and hard strata in the overlying strata. The change trend of the side abutment pressure of the two is basically the same, but the side abutment pressure of the free side of the roadway is obviously larger than the lateral abutment pressure of the mining side of the roadway. This shows that the existence of super-thick and hard strata makes the stress concentration, roadway mining will be more prone to damage. (4) The super-thick and hard strata will cause great impact on the stope after breaking. Compared with the stope without super-thick and hard strata, the damage degree is more severe, the elastic energy released is more, and the influence range is more extensive.

为了揭示巨厚坚硬岩层对采场支承压力与能量分布演化规律的影响,以杨柳煤矿某典型矿区为研究对象,使用数值模拟方法对其支承压力的变化规律与能量演化过程进行模拟研究。结果表明:(1)覆岩中存在巨厚坚硬岩层时,工作面中部及两侧的超前支承压力分别比无巨厚坚硬岩层时增加了9%和5%左右,这说明当覆岩中存在巨厚坚硬岩层时,采场中部及两侧长期处于高应力状态,当采场受到外力扰动时,会更容易导致矿震、冲击地压等动力灾害的发生;(2)覆岩中存在巨厚坚硬岩层时,其发生破断后采场超前支承压力变化曲线呈现断崖式下降,覆岩中无巨厚坚硬岩层时,相较于前者,其采场超前支承压力变化曲线则较为平缓;(3)随着工作面距离的持续推进,覆岩中有无巨厚坚硬岩层存在时,其临空帮支承压力峰值比回采帮支承压力峰值分别增加了3.60 MPa与3.39 MPa,两者侧向支承压力变化趋势基本保持一致,但巷道临空帮的侧向支承压力明显大于巷道回采帮的侧向支承压力,这说明巨厚坚硬岩层的存在使得应力集中,巷道回采会更容易发生破坏;(4)巨厚坚硬岩层破断后会对采场造成巨大的冲击,与无巨厚坚硬岩层采场相比,其破坏程度更加剧烈,释放的弹性能更多,影响范围也更加广泛。

为了揭示巨厚坚硬岩层对采场支承压力与能量分布演化规律的影响,以杨柳煤矿某典型矿区为研究对象,使用数值模拟方法对其支承压力的变化规律与能量演化过程进行模拟研究。结果表明:(1)覆岩中存在巨厚坚硬岩层时,工作面中部及两侧的超前支承压力分别比无巨厚坚硬岩层时增加了9%和5%左右,这说明当覆岩中存在巨厚坚硬岩层时,采场中部及两侧长期处于高应力状态,当采场受到外力扰动时,会更容易导致矿震、冲击地压等动力灾害的发生;(2)覆岩中存在巨厚坚硬岩层时,其发生破断后采场超前支承压力变化曲线呈现断崖式下降,覆岩中无巨厚坚硬岩层时,相较于前者,其采场超前支承压力变化曲线则较为平缓;(3)随着工作面距离的持续推进,覆岩中有无巨厚坚硬岩层存在时,其临空帮支承压力峰值比回采帮支承压力峰值分别增加了3.60 MPa与3.39 MPa,两者侧向支承压力变化趋势基本保持一致,但巷道临空帮的侧向支承压力明显大于巷道回采帮的侧向支承压力,这说明巨厚坚硬岩层的存在使得应力集中,巷道回采会更容易发生破坏;(4)巨厚坚硬岩层破断后会对采场造成巨大的冲击,与无巨厚坚硬岩层采场相比,其破坏程度更加剧烈,释放的弹性能更多,影响范围也更加广泛。

In order to reveal the influences of super-thick and hard strata on abutment pressure and the evolution law of energy distribution in stope, a typical mining area of Yangliu Coal Mine was taken as the research object, and the variation law of abutment pressure and energy evolution process were simulated by numerical simulation method. The results are concluded as follows. (1) When there are super-thick and hard strata in the overlying strata, the advance abutment pressure in the middle and both sides of the working face is increased by about 9% and 5% respectively compared with that without super-thick and hard strata. This shows that when there are super-thick and hard strata in the overlying strata, the middle and both sides of the stope are in a high stress state for a long time. When the stope is disturbed by external force, it is more likely to lead to the occurrence of dynamic disasters such as mine earthquake and rock burst. (2) When there are super-thick and hard strata in the overlying strata, the change curve of the advance abutment pressure of the stope shows a cliff-like decline after breaking. When there are no super-thick and hard strata in the overlying strata, the change curve of the advance abutment pressure of the stope is gentler than that of the former. (3) With the continuous advancement of the working face distance, the peak value of the abutment pressure of the free side is increased by 3.60 MPa and 3.39 MPa respectively compared with the peak value of the abutment pressure of the mining side when there are or are not super-thick and hard strata in the overlying strata. The change trend of the side abutment pressure of the two is basically the same, but the side abutment pressure of the free side of the roadway is obviously larger than the lateral abutment pressure of the mining side of the roadway. This shows that the existence of super-thick and hard strata makes the stress concentration, roadway mining will be more prone to damage. (4) The super-thick and hard strata will cause great impact on the stope after breaking. Compared with the stope without super-thick and hard strata, the damage degree is more severe, the elastic energy released is more, and the influence range is more extensive.

随着浅部煤炭资源逐渐匮乏,我国的煤炭开采也开始向深部转移[1-2]。但随着开采深度的增加,冲击地压也成为深部开采面临的主要问题之一[3-5]。当覆岩中存在巨厚坚硬岩层时,因其垮落步距长、岩层裂隙不易发育、承载能力强等特点,随着工作面的推进,存在于覆岩中的巨厚坚硬岩层不会随工作面的推进而垮落,而是悬跨在工作面上方,不断积聚着能量,当其发生破断时会突然释放大量的能量,诱发高能量矿震以及冲击地压等动力灾害,严重威胁井下的安全生产。
国内外学者对此进行了大量的研究,其中有著名的压力拱理论、砌体梁理论、关键层控制理论、铰接岩块假说等,学者们通过理论分析、力学分析、物理模拟试验、数值模拟试验等方法对采场中应力关系与覆岩运移规律进行了分析研究。其中,周楠等[6]通过构建坚硬岩层破断的薄板力学模型,给出了岩板正应力与破断尺寸的关系式,得到了坚硬岩层极限悬露尺寸与采区开采尺寸的关系。荣海等[7]通过对坚硬岩层结构进行分析,得出了相应的计算公式。LI等[8]通过研究开采速度对工作面以及上覆岩层的影响,建立了冲击地压的风险评价指标。张全等[9]认为高位厚硬岩层是强矿震的主要孕育、发生基地,而且深部煤层上覆往往孕育多层关键层,煤层采动易造成上覆多关键层协同断裂运动。左建平等[10]通过理论分析和数值模拟对岩层破断机理进行讨论,得到了3种破断机制、7类破断模式。卜庆为等[11]通过理论分析认为悬伸跨度、上覆岩层荷载是厚硬顶板采动承载和能量聚散演化的关键影响因素,上覆岩层荷载、自身厚度和强度是厚硬顶板极限悬伸跨度的关键影响因素。张震等[12]通过研究发现采场超前支承压力有从工作面中部向两端头扩展的动态迁移特性。谭云亮等[13]认为能量增大和应力突变是坚硬顶板型冲击地压前兆信息的两个主要特点。徐刚等[14]通过研究发现覆岩中存在巨厚坚硬岩层时,具有来压强增阻、来压步距大、偶有动载冲击等特征。
基于以上研究,本文以杨柳煤矿某典型矿区为研究模型,通过数值模拟试验对覆岩中存在巨厚坚硬岩层的采场进行研究,探究其支承压力与能量的演化规律,探讨回采时巨厚坚硬岩层对工作面造成的影响,对后续存在巨厚坚硬岩层采场的安全开采具有重要参考价值,以期为冲击地压等动力灾害的防治提供参考。
本文使用FLAC3D数值模拟软件进行研究,根据杨柳煤矿某典型赋存矿区条件建立的模型长×宽×高为710 m×390 m×301 m。开采过程中使用全采高全部垮落法,垮落高度为8 m。工作面的开采尺寸:宽180 m、回采距离500 m、开切眼宽10 m。建立的三维计算模型几何尺寸如图1所示。
回采巷道尺寸:宽为5 m、高为4 m,模型四周边界煤柱为100 m,所采煤层的埋深为600 m。边界条件:z轴高度为274 m,顶部向下施加8.15 MPa等效载荷,相当于326 m厚的上覆岩层向下施加压力,其余5面的位移约束均为法向约束,侧压系数为0.5,计算前对各个岩层的应力完成初始化。FLAC3D三维模型如图2所示。
为研究巨厚坚硬岩层对采场支承压力和巷道应力的影响,通过建立两个模型进行对比研究。模型一:巨厚坚硬岩层厚度为60 m; 与所采的煤层间距为80 m。模型二: 巨厚坚硬岩层用同等厚度的软岩来替代,其他条件不变。模型中各岩层岩性及其力学参数见表1 。
分析运算后的岩体应力及岩体位移数据,监测线的布置平面图如图3所示,监测线以及监测点布置在工作面宽度的1/2处。走向监测线与工作面推进方向平行,每隔15 m布设一条(以皮带平巷为准); 倾向监测线与皮带平巷垂直,每隔10 m布设一条。面向工作面推进方向,靠近皮带平巷的右侧煤体为临空帮,另一侧为回采帮。皮带平巷各位移监测点分别布置在各巷帮和顶底板的中央,监测点布置剖面图如图4所示。
选取两条监测线,测线L−h6图中位置位于工作面中部,测线L−h1图中位置位于距离工作面两侧15 m处,通过这两条监测线来研究工作面中部、两侧附近的超前支承压力受采场采动影响的变化规律。两条测线上的支承压力峰值随工作面推进距离的变化曲线如图5和图6所示,规律如下。
(1)由图5可知,随着工作面的推进,采场支承压力分为两个阶段。阶段Ⅰ:随着工作面距离的不断推进,覆岩中有巨厚坚硬岩层采场超前支承压力小于无巨厚坚硬岩层采场超前支承压力。阶段Ⅱ:随工作面距离的推进,覆岩有巨厚坚硬岩层采场超前支承压力大于无巨厚坚硬岩层采场超前支承压力。
(2)覆岩中存在巨厚坚硬岩层时,破断前其工作面中部及两侧超前支承压力发育较为平缓,两者保持在32.45~32.91 MPa和31.24~32.31 MPa。覆岩中无巨厚坚硬岩层时,两者超前支承压力保持在29.83~30.23 MPa和29.66~30.65 MPa。由图5可知,随着巨厚坚硬岩层长时间的悬跨导致应力集中并向煤壁的前方传递,故当覆岩中存在巨厚坚硬岩层时,采场中部以及两侧长期处于高应力状态,当采场受到外力扰动时,更容易导致矿震、冲击地压等动力灾害的发生。
(3)由图6可知,覆岩中存在巨厚坚硬岩层时,采场超前支承压力变化曲线呈现断崖式下降,覆岩中无巨厚坚硬岩层时,相较于前者,其超前支承压力的变化曲线则较为平缓。覆岩主关键层发生破断前后,有巨厚坚硬岩层时,工作面中部超前支承压力降低5.55 MPa, 两侧超前支承压力降低3.29 MPa; 无巨厚坚硬岩层时,工作面中部超前支承压力降低5.77 MPa, 两侧超前支承压力降低3.80 MPa。由以上数据可以看出,巨厚坚硬岩层的存在在一定程度上降低了关键层破断时能量释放的强度。
随着工作面推进距离的增加,由于工作面两侧存在回采巷道,无论覆岩中是否存在巨厚坚硬岩层,工作面两侧支承压力均小于工作面中部支承压力,这说明回采巷道的存在使得工作面两侧的支承压力向工作面中部转移。
选取图4中位于巷道右侧的监测线RW和位于巷道左侧的监测线LW,研究采场采动对巷道右侧和左侧超前工作面10 m、30 m和50 m处侧向支承压力造成影响的变化规律。
有无巨厚坚硬岩层下巷道侧向支承压力随工作面推进距离的变化曲线如图7所示。支承压力峰值变化规律如下。
(1)工作面开采初期,覆岩中存在巨厚坚硬岩层时,其巷道侧向支承压力与无巨厚坚硬岩层的巷道侧向支承压力基本上无差别,其巷道侧向支承压力在超前工作面10 m和30 m处略小于无巨厚坚硬岩层条件下的巷道侧向支承压力,在50 m处大于无巨厚坚硬岩层条件下的巷道侧向支承压力,这说明超前工作面位置不同,其影响程度也不同。
(2)随着工作面推进距离的增加,覆岩中存在巨厚坚硬岩层时,其巷道侧向支承压力一般要大于无巨厚坚硬岩层条件下的巷道侧向支承压力。而且随着工作面推进距离的增加,两者巷道侧向支承压力的差距也越来越大,说明巨厚坚硬岩层对巷道侧向支承压力的影响时间长,且随着时间推移其影响程度也越来越剧烈。
由图7可知,巷道两帮随工作面距离推进时其侧向支承压力变化规律基本一致。因此为研究采场采动对巷道靠近工作面内侧和工作面外侧支承压力的影响,选用其中一处研究即可,本文选用超前工作面10 m处的巷道侧向支承压力作为研究对象进行研究分析,巷道不同位置侧向支承压力随工作面推进距离的变化曲线如图8所示。
随着工作面推进距离的增加,巷道临空帮与回采帮的侧向支承压力变化趋势基本保持一致,但巷道临空帮的侧向支承压力明显大于巷道回采帮的侧向支承压力。覆岩中存在巨厚坚硬岩层时,临空帮支承压力峰值比回采帮的增加3.60 MPa;覆岩中无巨厚坚硬岩层时,临空帮支承压力峰值比回采帮的增加3.39 MPa。由此可见,覆岩中存在巨厚坚硬岩层时,两侧支承压力的压力差变大,增加了6.2%,这说明巨厚坚硬岩层的存在使得应力集中,巷道回采会更容易发生破坏。
在煤层未开采时,地下的煤岩体都处于原始的应力状态,随着工作面的采动,破坏了其原始的应力平衡状态,随着工作面的不断推进,煤岩体内的应力得到了重新分布,但当覆岩中存在巨厚坚硬岩层时,因厚度大、强度高的特点导致其不易垮落,长期的悬跨状态导致煤岩体长期处于高应力集中状态且逐渐发生弹性压缩变形,积聚大量的弹性能量,严重威胁井下的安全作业。
本文从观察煤岩体能量演化规律的角度出发,研究巨厚坚硬岩层破断前后采场弹性能的变化情况,并与无巨厚坚硬岩层存在的采场进行对比,观察巨厚坚硬岩层对采场周围弹性能的影响。
有无巨厚坚硬岩层下工作面中部弹性能峰值随工作面推进距离的变化曲线如图9所示。随着采场工作面距离的持续推进,煤层及上覆岩层内的弹性能经历了“积聚—释放—重新积聚”的周期变化过程。由图9可知,采场中的弹性能长时间处于应力集中状态,应力高且积聚大量的弹性能,在巨厚坚硬岩层第一次发生破断时,其峰值长期保持在2.7×105 J左右。大量的试验结果以及现场实践经验说明[15-16],微震活动的发生与弹性势能的积聚呈正相关关系,当微震活动保持一定水平时突然出现平衡期,此时期持续2~3 d后会发生严重的震动和冲击[17]。
在数值模拟中,巨厚坚硬岩层破断会释放大量的弹性能量,其数值为7.15×104 J,而无巨厚坚硬岩层的采场主关键层发生破断后释放的弹性能为4.92×104 J。由此可见,覆岩中巨厚坚硬岩层破断后会对采场造成剧烈的冲击,且其破断程度更剧烈,释放的弹性能更多,极易诱发冲击地压等动力灾害的发生。
因此,当覆岩中存在巨厚坚硬岩层时,会造成开采过程中支承压力以及弹性能的变异,使应力更加集中,不仅会对井下的安全开采造成巨大隐患,而且会产生更加强烈的井下灾害,加重了冲击地压等动力灾害的危险性。
覆岩中巨厚坚硬岩层破断前后的弹性能分布云图如图10所示。在上覆岩层主关键层发生破断前,其能量主要分布在采场的中间部分,当主关键层发生破断后,能量开始向采场两端集中,这是因为在发生破断前,上覆岩层的重量全部作用于采场,但是在发生破断后,底板对上覆岩层也起到了支撑作用,因此应力得到了重新分布。
图11为采场围岩塑性区分布云图,观察其演化情况可以得出如下规律。
(1)在主关键层破断之前,随着工作面距离的不断推进,煤层被采出后顶板失去支撑力开始向采空区一侧下沉,顶板发生大范围的剪切破坏,而未被开采的实体煤帮则作为顶板的支撑点,其顶板的应力不断垂直向下转移并集中,巨大的应力集中导致采场围岩发生变形破坏。在主关键层发生破断之后,应力重新分布,煤岩体内的弹性变形得到了恢复,但由于垂直应力的施加,岩体的强度得到了明显弱化,故没有新的塑性破坏发生。
(2)当模型1与模型2的采场前方围岩塑性区破坏深度均为7.5 m时,模型1中破坏网格数为11个,模型2中破坏网格数为10个。结合前面对支承压力和弹性能的分析可以得出,覆岩中存在巨厚坚硬岩层时,其围岩的破坏程度更大、范围更广。
图12为巷道围岩塑性区分布云图。模型1和模型2的围岩塑性区破坏深度分别为5 m、2.5 m,模型1的破坏网格数量大于模型2的破坏网格数量,与前文所述结合更能说明巨厚坚硬岩层的破断会对工作面与巷道造成严重的影响。
(1)覆岩中存在巨厚坚硬岩层时,其工作面中部及两侧超前支承压力分别保持在32.45~32.91 MPa和31.24~32.31 MPa;覆岩中无巨厚坚硬岩层时,两者超前支承压力保持在29.83~30.23 MPa和29.66~30.65 MPa。与无巨厚坚硬岩层采场相比,工作面中部超前支承压力增加了9%左右,两侧超前支承压力增加了5%左右。这说明当覆岩中存在巨厚坚硬岩层时,采场中部及两侧长期处于高应力状态,当采场受到外力扰动时,会更容易导致矿震、冲击地压等动力灾害的发生。
(2)当覆岩中存在巨厚坚硬岩层时,采场中部和两侧长期处于高应力状态,在巨厚坚硬岩层破断前,采场中部和两侧超前支承压力均大于无巨厚坚硬岩层的采场,覆岩破断后,采场超前支承压力的变化曲线呈现断崖式下降,而覆岩中无巨厚坚硬岩层时,相较于前者,其超前支承压力的变化曲线则较为平缓。
(3)随着工作面距离的持续推进,覆岩中存在巨厚坚硬岩层时,临空帮支承压力峰值比回采帮增加3.60 MPa;当覆岩中无巨厚坚硬岩层时,临空帮支承压力峰值比回采帮增加3.39 MPa,两者侧向支承压力变化趋势基本保持一致,但巷道临空帮侧向支承压力明显大于巷道回采帮侧向支承压力,这说明巨厚坚硬岩层的存在使得应力集中,巷道回采会更容易发生破坏。
(4)随着采场工作面距离的持续推进,煤层以及上覆岩层内的弹性能经历了“积聚—释放—重新积聚”的周期变化过程。在巨厚坚硬岩层发生破断前,采场中部弹性能长时间处于应力集中状态,应力高且积聚大量的弹性能。巨厚坚硬岩层破断后积聚的能量会突然释放,对采场造成巨大的冲击,与无巨厚坚硬岩层采场相比,其破断程度更加剧烈,释放的弹性能更多,其对工作面与巷道造成的破坏更加严重,范围也更加广泛。
