摘要
应根据磁窑沟矿10号煤层的地质条件,整层一次采全高综放采场的开采情况,按照预测综放采场煤岩组合移动结构及力学模型、综放支架工作阻力、综放面支架可缩量及最大最小高度参数、综放支架放煤口等数据,对综放开采支架工作阻力进行确定。
Based on the geological condition of No.lO coal seam in Ciyaogou mine and mining situation of overall height mining of the seam in one time, the working resistance of mining support is determined according to data, including combined moving structure and mechanical model of the mining field, working resistance of the support, shrink quantity of the support, the maximum and the minimum height parameters, and drawing opening position of the support.
