摘要
为了减少护巷煤柱损失,扭转采掘衔接紧张的不利局面,寺河二号井97307薄煤层工作面采用切顶卸压自成巷技术,通过巷道超前补强、聚能爆破、采空区堵漏等诸多技术措施,成功实现工作面区段之间无煤柱开采,现场应用效果良好。
In order to reduce the loss of coal pillars in the protective roadway and reverse the unfavorable situation of tight mining and excavation connection,the technology of roof cutting pressure relief roadway excavation has been adopted in No.2 well of 97307 thin coal seam working face,Sihe Colliery.Various technical measures such as advance reinforcement of the roadway,energy accumulation blasting,and goaf plugging have taken to realize coal pillar free mining between the working face sections,whose field application effect is good.
