摘要
同家梁矿针对综合机械化采煤造成的残余煤炭和遗留的小煤柱的回收问题,制定了边角区域开采方案,确定了工作面布置原则,遇特殊地质条件时的支护方式、回采措施及配套设备选择原则。制定了在复杂区域开采时注马丽散和在超前补支木点柱的联合支护方法,为类似地质构造的矿井提供了参考。
In view of the residual coal and legacy of small coal column recovery problem caused by the comprehensive mechanized coal mining in Tongjialiang coal mine, formulated the comer region mining scheme, determined the working face layout principle, and the excavation and mining measures and ancillary equipment selection principle meeting the special geological conditions. In the complex region, the combined support method of the grouting Ma Li and in the advance of the supporting column is developed, which provides a reference for the similar geological structure of the mine.
