摘 要:以某煤矿101综放工作面为例,通过对综放工作面的基本情况分析,认为其存在顶煤放落困难、放出率低的问题。针对上述出现的情况,通过现场实测、统计分析、数值模拟等一系列研究手段,从优化回采工艺参数入手,对101综放工作面的回采率和回采效果进行了探讨,研究结果与方法可对该矿提升工作面的回采率以及下一步矿井安全高效开采提供依据。Taking the 101 fully mechanized top coal caving face of a certain coal mine as an example,through the analysis of the basic situation of the fully mechanized top coal caving face,it is believed that there are difficulties in top coal caving and low caving rate.In response to the above situation,a series of research methods such as on-site measurement,statistical analysis,and numerical simulation were used to optimize the mining process parameters,and the mining rate and mining effect of the 101 fully mechanized caving face were discussed.The research results and methods can provide a basis for improving the mining rate of the working face and the safe and efficient mining of the next step of the mine.
