帮部桁架支护技术在巷道压力区治理中的应用

Application of the support technology of the support technology in the control of the roadway pressure area

该文主要介绍了在回采工作面巷道沿空窄煤柱侧帮部压力区治理中所采用的方法及支护技术,通过把顶板桁架支护技术灵活运用到帮部,形成帮部桁架支架方式,成功治理了沿空窄煤柱巷道帮部变形量大的问题,同时,采用喷浆与帮部桁架形成联合支护的方式,不但解决了压力区帮部治理,而且避免了采区空有害气体的溢出,保证了工作面安全回采。

This paper mainly introduces the used method and the supporting technology in the pressure area treatment of the roadway wall that is near the narrow coal pillar along the gob, through flexibly used the roof truss support technology to the wall, successfully solve the large deformation problem of roadway along the gob, at the same time, the use of the truss and the spraying combined support way, not only solve the governance for the pressure zone, and avoid the harmful gas overflow of gob, and ensure the safety in working face mining.
