综放面过联络巷技术研究与实践

Research and practice of the technology mining through crossheading of fully mechanized caving faces

根据金川煤矿煤层松软破碎、地质构造复杂的特性,在综放面过联络巷前,采取了对联巷预先加固、设备检修维护、工作面伪斜调整等准备工作。同时在通过联巷的过程中进行矿山压力分析,并对出现的主要技术难题进行系统的研究,采取了相应治理对策,确保了工作面安全、快速的通过联巷,取得了良好的技术经济效益,为以后综放面过联络巷积累了宝贵的经验。

According to jinchuan soft coal seam broken, complex geological structure characteristics, adopted in fully-mechanized face before connection, couplet lane reinforcement, equipment maintenance and working face in advance preparations for pseudo inclined adjustment etc. At the same time through the analysis of the mine pressure in the process of al lane, and the main technical problems of the system the research, take the corresponding control measures, to ensure the safe and fast face through the lane, achieved good technical and economic benefits, for fullymechanized face after a connection has accumulated valuable experience.
