神华神东布尔台煤矿改变开采工艺后,需要对液压支架支护参数进行优化,理论分析综放端面煤岩体片帮冒落与支架参数支架关系,运用数值模拟方法,建立综放端面煤体片帮冒顶模型,对液压支架参数与端面煤岩体片帮冒落相互关系进行模拟。结果表明支架工作阻力与梁端距是影响支架控制效果的关键参数。
Shenhua God East Bo Er Tai coal mine after changing the mining process, the need to optimize the hydraulic support parameters, the theoretical analysis of coal face caving and coal caving to support the relationship between the stent, the use of numerical simulation method to establish the face of fully mechanized coal face Piece to help the roof model, the hydraulic support parameters and the face of coal and rock fragments to help each other to simulate the caisson. The results show that the working resistance of the bracket and the end of the beam are the key parameters that affect the control effect of the bracket.
