邻采空区超厚复杂煤层的采掘技术

Mining Technology of Ultra-thick and Complex Coal Seam Adjacent Goaf

针对邻采空区超厚复杂煤层在采掘过程中出现的突出问题,提出了对综放工作面邻采空区易发生顶板断裂下沉和矿压显现强的巷道段采取超前支护和补强支护措施,从而确保采掘作业的正常进行,有效解决了邻采空区超厚复杂煤层采掘技术难题,为煤矿生产的安全进行提供了保障。

For the prominent problems of adjacent goaf ultra-thick and complex coal seam appeared in the process of mining,we puts forward the forepole and reinforcing supporting measures to occur often in the roof-breaking sink and mining pressure show strong section that is a certain roadway of fully mechanized caving face adjacent goaf,which ensures the normal mining operation,solves effectively the adjacent goaf ultra-thick and complex coal seam mining technical problems,and provides the guarantee for the production of coal mine safety.
