Aiming at the characteristics of roadway surrounding rocks in Baiyinhar mine, such as hard lithology, severe alteration and extremely poor stability, a secondary support scheme for the roadway based on the distribution of the plastic zones was proposed. For the fractured surrounding rocks, based on the results of the point load test and the relevant shaft construction data of the Baiyinhar mine, the physical and mechanical parameters of the rock mass were calculated according to the Hoek-Brown strength criterion. The plastic zone range of the arched roadway was calculated using three equivalent circle radius methods combined with the Fenner formula and the Drucker-Prager (D-P) criterion formula, and the Kastner approximate solution for the plastic zone boundary of the surrounding rock of a circular hole under a non-uniform stress field was obtained. The displacement, stress, and plastic zone distribution after excavation, as well as the effect of the original support, were obtained using numerical simulation. According to the plastic zone distribution of the roadway surrounding rock under the original support, the secondary support for the roof, top corners, and floor of the roadway was conducted. The results show that the equivalent circle radius method of the circumscribed rectangle and the D-P criterion are more suitable for calculating the plastic zone of the roadway in Baiyinhar mine. Combined with numerical simulation, it is found that gold-bearing altered rock is predominantly distributed in the top corners of the roadway. After conducting the secondary support, the deformation of the surrounding rock at the roof and floor was significantly reduced from the original 23 mm to approximately 8 mm and 10 mm, respectively. The stress concentration in the roof was also reduced, and the range of the plastic zone was significantly decreased, which helps to prevent shear failure of the roadway surrounding rock.

针对白音哈尔矿巷道围岩岩性坚硬,蚀变严重,稳固性极差的特点,提出了对巷道按照塑性区分布进行二次支护。对于破碎围岩,基于点荷载试验结果以及有关白音哈尔矿建井资料,根据Hoek-Brown强度准则,计算得到了岩体的物理力学参数。利用三种等效半径方式与芬纳公式、Drucker-Prager(D-P)准则公式计算拱形巷道的塑性区范围,并且计算出非均匀应力场中圆孔围岩塑性区边界卡斯特奈近似解。采用数值模拟的方法得到开挖以后的位移、应力、塑性区分布以及原始支护效果。根据原始支护下的巷道围岩塑性区分布,对巷道的顶板、顶角以及底板进行二次支护。结果表明,矩形外接圆等效半径法、D-P准则更加适用于白音哈尔矿巷道塑性区计算,结合数值模拟可知,含金蚀变岩较多地分布于巷道顶角区域。基于巷道塑性区分布进行二次支护后,巷道顶板与底板围岩变形量有了明显减小,顶、底板位移由原来的23 mm分别减小到8 mm、10 mm左右,且顶板应力集中减小,塑性区范围显著减小,有助于防止巷道围岩发生剪切破坏。
