急倾斜中厚-厚煤层巷道放顶煤计算机模拟

The Computer Simulation of Roadway Sub-level Caving of Steep Medium Thickness～Thich Seam

在工业性试验的基础上建立了急倾斜中厚－厚煤层巷道放顶煤计算机模拟模型，模拟了煤厚、分段高度、放煤口距离对顶煤回收率的影响。

The model computer simulation for roadway sub-level caving of steep medium thickness～thick seem was set ip on the basis of industrial test It is simulated that the recovery rate of roof coal was influenced by the thickness of seam, the height of caving level and the distance of chute Thus, the optimal height of caving level was determined
