不规则块段综放工作面高效回采技术研究

High Efficiency Mining Technology of Fully Mechanized Caving Face in Irregular Block

综放开采是厚及特厚煤层开采的一种高效方法。在一些特殊情况下,综放工作面并不能规则布置。因此,如何实现不规则块段综放工作面的高效回采是一个重要的课题。以铺龙湾煤矿8102综放工作面为例,重点分析了综放工作面的调斜、扩采和缩采施工方法,可以为不规则块段综放工作面的高效回采提供一定的技术参考。

Fully mechanized caving mining is an efficient method for mining thick and extra thick coal seams.In some special cases,the fully mechanized caving face cannot be arranged regularly.Therefore,how to realize efficient mining of fully mechanized caving face in irregular block is an important subject.Taking 8102 fully mechanized caving face of Pulongwan Coal Mine as an example,this paper emphatically analyzed the construction methods of slope adjustment,expanding mining and shrinkage mining of fully mechanized caving face,which can provide certain technical reference for efficient mining of fully mechanized caving face in irregular block.
