煤矿工作面沿空留巷支护技术研究

Research on Supporting Technology of Coal Mine Working Face along the Lane

沿空留巷支护作为煤矿巷道支护技术的一种,已在各大煤矿中进行了推广,但在实际应用中还存在不足,在作业中支护强度不达标时存在安全隐患。因此,在结合沿空留巷支护技术特点及支护形式基础上,对其存在问题进行了分析,提出了沿空留巷的改进措施并进行应用效果评价,验证了沿空留巷支护技术的可行性及可靠性。

As a kind of roadway support technology in coal mine,roadway support along goaf has been popularized in various coal mines.However,there are still shortcomings in practical application,and there are hidden dangers when the support strength is not up to standard in operation.Therefore,on the basis of combining the technical characteristics and supporting forms of the roadway along the goaf,the existing problems are analyzed,and the improvement measures and application effect evaluation along the roadway are put forward.The feasibility and reliability of the roadway support technology are verified.
