In order to explore the effect of high fluid slurry materials on the micromechanical properties of coal, the transition area formed by different slurry materials and coal after grouting was scanned by scanning electron microscopy (SEM). Nanoindentation tests were carried out to analyze the effects of high fluid slurry materials on the microstructural characteristics and micromechanical properties of coal. Structural defects existed in the consolidated surface after grouting of ordinary cement materials. In view of this, the structural modification and mechanical strengthening mechanism of the transition area of the heterogeneous body were analyzed. The results show that the mechanical properties of the transition area between the high flow grouting material and the coal body are the weakest in the heterogeneous structure. This area is easy to break. The indentation modulus and indentation hardness in the transition zone between high flow grouting material and coal increase with the increase of mechanical properties of coal structure surface. After the ordinary cement grouting, the transition zone between the material and the coal body is large. The crystal density is low, there are obvious cracks between the material and the coal body, and the micromechanical properties are weak. After grouting, the high flow grouting material has close microstructure in the transition zone with coal. The transition zone with consolidated surface is small. Meanwhile, the interface transition zone (ITZ) has good micromechanical properties. These characteristics are helpful to improve the ability of gas extraction borehole deformation resistance.

为探究高流态浆体材料注浆后对煤体微观力学性能的影响,首先通过扫描电镜(SEM)扫描不同注浆材料注浆后与煤形成异质体的过渡区,并进行纳米压痕试验,进而分析高流态浆体材料对煤体微观结构特征以及微观力学性能的影响;然后,针对普通水泥材料注浆后,固结面存在的结构缺陷,分析高流态浆体材料对异质体过渡区的结构改性与力学强化机制。结果表明:高流态注浆材料与煤体过渡区的力学性能是异质体结构中最弱的区域,容易发生破断;高流态注浆材料与煤过渡区的压痕模量、压痕硬度,均随着注浆煤体结构面力学性能的提高而增大;普通水泥注浆后,与煤体过渡区的范围较大,晶体密度低,材料与煤体之间有明显的裂隙,微观力学性能较弱;高流态注浆材料注浆后,与煤过渡区的范围微观结构紧密,固结面过渡区的范围较小,界面过渡区(ITZ)微观力学性能较好,有助于提升瓦斯抽采钻孔抵御塌孔变形的能力。

为探究高流态浆体材料注浆后对煤体微观力学性能的影响,首先通过扫描电镜(SEM)扫描不同注浆材料注浆后与煤形成异质体的过渡区,并进行纳米压痕试验,进而分析高流态浆体材料对煤体微观结构特征以及微观力学性能的影响;然后,针对普通水泥材料注浆后,固结面存在的结构缺陷,分析高流态浆体材料对异质体过渡区的结构改性与力学强化机制。结果表明:高流态注浆材料与煤体过渡区的力学性能是异质体结构中最弱的区域,容易发生破断;高流态注浆材料与煤过渡区的压痕模量、压痕硬度,均随着注浆煤体结构面力学性能的提高而增大;普通水泥注浆后,与煤体过渡区的范围较大,晶体密度低,材料与煤体之间有明显的裂隙,微观力学性能较弱;高流态注浆材料注浆后,与煤过渡区的范围微观结构紧密,固结面过渡区的范围较小,界面过渡区(ITZ)微观力学性能较好,有助于提升瓦斯抽采钻孔抵御塌孔变形的能力。

In order to explore the effect of high fluid slurry materials on the micromechanical properties of coal, the transition area formed by different slurry materials and coal after grouting was scanned by scanning electron microscopy (SEM). Nanoindentation tests were carried out to analyze the effects of high fluid slurry materials on the microstructural characteristics and micromechanical properties of coal. Structural defects existed in the consolidated surface after grouting of ordinary cement materials. In view of this, the structural modification and mechanical strengthening mechanism of the transition area of the heterogeneous body were analyzed. The results show that the mechanical properties of the transition area between the high flow grouting material and the coal body are the weakest in the heterogeneous structure. This area is easy to break. The indentation modulus and indentation hardness in the transition zone between high flow grouting material and coal increase with the increase of mechanical properties of coal structure surface. After the ordinary cement grouting, the transition zone between the material and the coal body is large. The crystal density is low, there are obvious cracks between the material and the coal body, and the micromechanical properties are weak. After grouting, the high flow grouting material has close microstructure in the transition zone with coal. The transition zone with consolidated surface is small. Meanwhile, the interface transition zone (ITZ) has good micromechanical properties. These characteristics are helpful to improve the ability of gas extraction borehole deformation resistance.
