泉店煤矿近距离煤层群联合开采方式的实现

Realization of Close Distance Coal Seam United Mining Way in Quan-dian Coal Mine

为实现近距离煤层联合开采,分析了开采工作面采动岩层底板移动与超前破坏区间相互作用的关系,提出了近距离煤层群联合开采常规错距开采模型。从理论上给出近距离煤层群联合开采下的工作面合理错距计算公式,避免因上、下煤层工作面间距设置不合理,造成上下采场不能正常开采的情况。

In order to realize close distance coal seam united mining, analyzes the relationship between exploration coal seam mining rock bottom plate moves and advance break section. The close coal seam groups united mining common dislocation model is proposed. The reasonable dislocation computing formula is given out from theory. This method can avoid unreasonable setting distance of up and low coal seam, which causes abnormal exploration.
