文家坡矿42盘区区域上行开采UDEC数值模拟研究

Research on UDEC Numerical Simulation of Upward Mining in 42 Panel Area of Wenjiapo Mine

从文家坡矿42盘区区域煤层赋存的条件出发,以3煤、1煤上行开采为研究背景,运用UDEC数值模拟软件对42盘区区域上行开采对3煤、1煤的影响进行分析,数值模拟结果与理论计算基本一致,采取一定的技术措施后3煤和1煤可以进行上行开采,为42盘区区域上行开采提供了理论依据。

Based on the occurrence conditions of coal seam in the 42 panel area of Wenjiapo mine,taking the upward mining of 3 coal and 1 coal as the research background, the UDEC numerical simulation software is used to analyze the influence of upward mining on 3 coal and 1 coal in the 42 panel area, the numerical simulation results are basically consistent with the theoretical calculation,after taking certain technical measures, 3 coal and 1 coal can be upward mined, which provides a theoretical basis for upward mining in the 42 panel area.
