清河煤矿分层开采探讨

在中厚煤层实行分层开采时,下分层巷道掘进过程中与上分层巷道经常发生漏通,为满足通风及掘进工作面人员施工的安全,必须采取上下交错巷道漏通支护措施。以清河煤矿1803下运输顺槽掘进工作面为例,详细介绍了中厚煤层实行分层开采的措施和方法。

Probe into the Slicing Method Adopted in Qinghe Coal Mine

In the case of adopting the slicing method in medium coal seam,the leakage often occurs between upper slicing roadway and lower slicing roadway in the course of excavating of lower slicing roadway.In order to satisfy the ventilation and workers＇ safety in the excavation on working face,the interlaced roadway leakage support measure must be adopted.Taking the working face 1803 of Qinghe Coal Mine as an example,this paper introduces in detail the measures and methods for implementing the mining in slices in medium coal seam.
