摘要
在对急倾斜煤层俯伪斜分段密集支柱采煤法和直线长壁采煤法的巷道和工作面矿压显现规律进行了现场观测和室内试验研究的基础上,对比了两种采煤法矿压显现规律,分析得到了俯伪斜分段密集支柱采煤法能大大缓和矿压显现不均匀现象的机理,探讨了采用该种采煤法时,工作面支架分段密集布置参数的合理性,为工作面优化设计和矿压控制提供了科学依据。
Based on the study of ground pressure in mining face and roadway through experiments in site and model testing in lab, the behaviors of ground pressure are compared for the pitching oblique underhand mining and straight long-wall mining. The reasons of uneven ground pressure are obtained for pitched oblique underhand mining. Meanwhile, the adaptable parameters in mining face of pitching oblique underhand mining are discussed, and they could be used for the control of ground pressure and optimum design.
