介绍了 4.5 m厚煤层综采放顶煤工作面在“三软”围岩、煤层倾角较大、瓦斯涌出量大的条件下 ,顺利地通过落差 3～ 6m断层的实践 ,以及过断层调整工作面的推进方向、控制支架的仰俯角等准备工作 ,过断层时煤壁的超冒管理 ,支架和运输机的调整 ,煤质管理 ,工作面上隅角的瓦斯治理等一系列技术方案和主要措施。以便为矿区在特殊条件下的综放开采提供借鉴。
The fully mechanized top coal caving face with a thickness of 4.5 m is introduced in the condition of “three soft” surrounding rock with large coal seam inclination angle and large gas emission. Through the practice of falling 3 ~ 6m fault and fault adjustment The direction of advancement of the working face, the preparation of the control elevation angle of the support, the overcapacity management of the coal wall when crossing the fault, the adjustment of the support and the transport plane, the coal quality management and the gas treatment at the upper corner of the working face, and a series of technical solutions and major Measures. In order to provide reference for the mining in fully mechanized caving under special conditions.
