摘 要:针对龙华煤矿20112综采工作面过空巷存在顶板压力较大、支架工作阻力变化复杂等问题,结合龙华煤矿20112综采工作面实际情况,设计了2种综采工作面过空巷支护技术方案,对其经济性进行了对比,并用于实际生产。实践表明:该方案使工作面过空巷受采动影响较小,无顶、帮变形现象,加快了超长工作面的安全快速回采,带来经济效益的同时也为超长工作面过空巷技术提供了借鉴。Aiming at the problems such as large roof pressure and complex change of support resistance in 20112 fully-mechanized working face of Longhua coal mine, combined with the actual situation of20112 fully-mechanized working face of Longhua coal mine, two kinds of supporting technology schemes of fully mechanized working face of Longhua coal mine are designed, and their economy is compared and applied in actual production. The practice shows that the scheme makes the goaf crossing of the working face less affected by mining, has no roof and wall deformation, speeds up the safe and rapid mining of the ultra-long working face, brings economic benefits and provides reference for the goaf crossing technology of the ultra-long working face.
