机采高度对工作面超前支承压力的影响研究
|
摘要
依据某矿8105大采高综放工作面具体地质生产条件,应用文献检索、数值模拟等工具,研究了工作面机采高度增加后对诸如超前支承压力、端面煤体塑性区等矿压显现参数的影响情况,得出了具体的实验结论。
According to the specific geological production conditions of the No. 8105 fully mechanized top-coal caving face in a certain mine, by using the tools of literature retrieval and numerical simulation, the paper studies the effect of the mining height of the working face on such as the leading supporting pressure after the mining height is increased.The influence of the rock pressure parameters such as plastic zone of the coal body on the end face is analyzed and the concrete experimental results are obtained.
