摘要
叙述了国内外煤层底板破坏规律研究的现状。根据矿区实地数据资料建立模型,对不同推进距离、不同水压、不同隔水层厚度条件下的底板破坏特征进行模拟分析。
Described the status of coal seam floor destructive laws research at home and abroad. Build models according to the mine field data, and make simulation analysis of the seam floor destructive laws under the conditions of different advancing distance, different water pressure, and different aquiclude thickness.
