断层破碎区回采巷道的围岩控制问题是煤炭安全开采面临的重要课题之一。受到断层等特殊地质构造的影响，断层影响区的巷道煤岩体的力学性态发生了畸变，严重制约回采巷道稳定性和安全开采。 针对神华新疆公司屯宝煤矿多断层地质情况，采取现场工程地质特征调查分析来确定所研究工作面回采巷道围岩物理力学性质以及1193综放工作面与相邻工作面的空间位置关系；借助Hoek-Brown准则构建巷道围岩力学模型，分析巷道围岩深层临界失稳范围并且推导其计算公式，得出了其围岩深层临界失稳范围的理论值为2.24m；通过在多种不同类型监测仪器相结合的综合监测手段，揭示了屯宝煤矿断层破碎区回采巷道煤岩体的变形规律，认为断层影响区内回采工作面受断层附加应力与超前支承应力的双重叠加作用影响，回采巷道煤柱变形较煤壁侧尤为严重。确定了1193综放工作面动压超前影响范围为34.0m，超前支承应力的峰值位置约为5.0m，巷道煤壁侧的煤岩体深层临界失稳范围为2.33m，顶板侧的煤岩体深层临界失稳范围为2.24m。借助FLAC3D有限元数值模拟对区段煤柱尺寸进行优化，结合现场实际开采特征确定煤柱的合理宽度；最终确定了巷道煤岩体深层临界失稳范围，对1193工作面回采巷道的支护方案及支护参数进行了优化，选择更适合的锚杆、锚索与锚网等支护方式，在局部破碎范围内使用“锚杆+锚注+W钢带+钢梁”的方式加强支护，保障回采巷道在断层影响范围内的稳定，实现了安全开采。 本论文成果对于断层影响区回采巷道稳定性控制具有指导意义，对于类似条件下的矿区安全开采起到了借鉴意义。

The issue on surrounding rocks control in fault broken zone is premierlly needed to be paid more consideration when it terms to production safetily. Because of the influence of faults, the mechanical properties of roadway coal-rock changed, that severely restricts roadway stability and mining securitily. Taken 1193 working face roadways in falut broken zone of Tunbao colliery into consideration, the sophisticated analysis methods were here to study the supporting technics and deformation rule of roadway surface. Through site engineering geological investigation, we got much information about the spatial relationship between 1193 mechanized caving face and adjacent face. The lithology and physical mechanical properties of roadway surrounding rock were gathered from physical and mechanical experiments on surrounding rocks. With the help of Hoek-Brown criterion, roadway’s mechanical model was created to analyze the internal critical unstability range in roadway and its formular was derived. Taken the physical mechanical properties of surrounding rock in 1193working face roadway into consideration, it is dedicated that the internal critical unstability range in roadway was 2.24m. Through comprehensive site monitoring methods, the results are dedicated that larger deformation occurred at pillar side compared with the coal seam side; the influential range of dynamic pressure in 1193 working face is 34.0m and the peak value is 5.0m caused by superimposed stress, which includes faults additional stress and advanced bearing stress; it shown that the range reached 2.33m at the coal seam side and 2.24m at roof side. Finite element numerical simulation software -FLAC3D was here to optimalize sectional coal size, when taken the site engineering geological investigation into consideration. Finally, through reansonable detection on influential range of dynamic pressure and internal critical destabilization range in fault broken zone, the supporting parameters were optimized after comprehensive comparison between mechanical analysis and in-site detection. Much more reasonable bolt, anchor, anchor net and other supporting materials were applied to maintain the safety in mining through fault broken zone. This new optimized supporting design was proposed to improve the surrounding rock’s own strength and fully realize its self-supporting capability in the roadways. Our research could not only ensure the safety in Tunbao mine but also provide a meaningful effect to other mines with similar geological situation.
