为了及时准确地掌握综采工作面回采期间支架的受力状况和来压特征,运用国内先进的矿压在线监测系统对色连一矿8101综采面支架受力过程进行现场观测,得出了支架工作阻力随工作面推进度的变化关系以及直接顶与老顶的来压步距。并从理论层面分析了顶板垮落的力学特征,为后续工作面的顶板管理和巷道支护提供重要参考。
In order to timely and accurately grasp the mechanical and compressive characteristics of support during the mining of fully mechanized coal mining face, the on-site observation of the mechanical behavior of 8101 fully mechanized coal mining face with the advanced domestic on-line monitoring system was carried out, The working resistance of the supporter changes with the advancing degree of the working face and the pressure step distance between the direct top and the old top. The mechanical characteristics of roof caving are analyzed theoretically, which provide important reference for the roof management and roadway support of the following working face.
