薄煤层野青复合顶板的支护技术研究

Thin Coal Seam of Wild Green Composite Roof Supporting Technology Research

根据陶一煤矿野青煤层的灰岩顶板赋存条件的差异,对不同条件的灰岩顶板采取了不同的支护方式,并借助巷道顶板与断面变形观测,完善了巷道顶板支护技术。同时,在施工中采用了综掘作业方式,减少了掘进对灰岩顶板的破坏,提高了掘进单进与工效,加快了野青薄煤层的开拓准备,缓解了矿井采掘生产衔接紧张局面。

According to Handan mining wild green layers of limestone roof occurrence condition difference,different way of roof support was taken.With observation of roadway roof and section deformation,the roadway roof support was consummated.Meanwhile,comprehensive tunneling practices in construction was adopted,the damage to the limestone roof was reduced.The technology the single heading and the work efficiency were improved.The technology quickened the wild green thin seam pioneering and alleviated the coal mining production.
