摘要
以神东矿区石圪台煤矿31201工作面为研究对象,根据围岩物理力学参数,构建平面相似模拟模型。在实验过程中分析模拟支架的力学特征,支架额定工作阻力18 000 k N能够满足生产需要。相似模拟实验结果能够为浅埋煤层大采高工作面安全高产高效生产及支架选型、超前支护步距确定提供参考。
Taking 31201 working face in Shigetai coal mine of Shendong mining area as a study object, according to the physical and mechanical parameters of surrounding rock, the plane similar simulation model was constructed. The mechanical characteristics of simulation supports are analyzed in the process of experiment,the rated work resistance 18 000 kN can satisfy the production requirement. Similar simulation experiment results can provide the reference for high production and efficiency in shallow seam mining height safety production and the selection, forepole support interval determination.
