| 摘 要： | 通过理论计算得出工作面开采覆岩破坏高度,利用关键层理论分析覆岩破坏、移动、控制规律,并对井筒下覆工作面回采对斜井的影响进行了论证,为工作面安全、高效回采提供了理论支持。现场矿压观测数据结果表明,斜井没有受到下覆工作面开采的影响。

| Abstract: | With the overburden strata failure height due to the coal face mining obtained by the theoretical calculation,the key stratum theory was applied to analyze the overburden strata failure,movement and control law and to verify the coal mining in seams underneath the mine shaft affected to the mine inclined shaft,which could provide the theoretical support to the safety and high efficient mining of the coal mining face.The results of the site mine strata pressure measured data showed that the mine inclined sha... |
