摘要
深部开采条件下,煤矿巷道的有效支护是保证矿井安全高效生产的重要因素。运用相似材料模拟试验和现场工业性试验,研究鹤壁煤电股份有限公司八矿深部倾斜岩层水平巷道围岩破坏特征,分析随加载压力的增大和不同支护方式下巷道围岩位移变化规律、巷道围岩裂隙演化特征及分布特征等,得出适合该地质条件下较为有效的支护方案。研究结果能更直观了解巷道围岩表面及其内部裂隙发生、发展的过程及其联系,为巷道支护参数的合理选取提供依据。该研究方法和一些结论可为同类的研究提供一定的借鉴。
In deep mining, the effective roadway support is an important factor to ensure the safety mining, high production and efficiency. Based on the similarity simulation test and the field test, the fracture characters of the horizontal roadway are studied, which is located in deep tiled strata in Coal Mine No.8 of Hebi Coal Power Ltd.. The law of displacement of roadway, under different applying loads, and the characteristics of development of fracture in roadway and distributions are analyzed. For this geological condition, the more effective support plan is figured out. The study result can be used for understanding the occurrence, development and relationship of the surface of roadway and interior cracks. Based on the results, the support parameters of the roadway can be chosen reasonably. The study methods and results can be used as reference for other similar studies as well.
