摘要
对我国近年来出现并引起重视的端帮压煤情况进行了研究与分析。针对我国内蒙西部某露天煤矿的实际开采情况,采用FLAC3D软件对采硐稳定性进行了动态模拟,根据MarkBieniawski公式对永久煤柱、支撑煤柱的合理宽度进行了验算。分析研究了该矿端帮开采顺序、端帮采场开采布置、给出开采参数。
The article researches and analyzes the end slope compressed coal condition in recent years. Aiming at the actual mining situation in the open-pit mine of Inner Mongolia west, the article adopts FLAC3D software to dynamically simulate mining tunnel stability, calculates the reasonable width of permanent coal pillar and supporting coal pillar according to Mark-Bieniawski formula, and researches mining sequence, mining layout, mining parameters of end slope in the mine.
