昌恒煤焦有限公司9101工作面煤层为特厚煤层,埋深浅且赋存条件稳定,工作面采用走向长壁综合机械化放顶煤开采。作为整合后矿井的首个综放工作面,研究其顶板压力显现规律非常重要。通过现场监测,结合矿山压力与岩层控制理论,对9101综放工作面初采期间矿压规律进行分析,并结合支架受力状况,分析了9101综放工作面初采期间顶板来压的规律和特征,为矿井接替工作面的安全高效回采提供了科学依据。 The coal seam of 9101 face of Changheng Coal Coke Co., Ltd. is a thick and thick coal seam with shallow depth and stable conditions of occurrence. The working face adopts the longwall comprehensive mechanized caving mining. As the first fully mechanized coal mining face after integration, it is very important to study the law of roof pressure. Through the on-the-spot monitoring, combined with the theory of mine pressure and rock control, the law of rock pressure during initial mining of 9101 fully mechanized top coal caving mining face is analyzed. Combined with the force status of the support, the law of roof pressure during initial mining of 9101 fully mechanized top- Features, provide a scientific basis for the mine to replace the safe and efficient mining face.
