摘要:
运用固流耦合理论对某矿东四采区11-2煤远距离下保护层开采过程中的被保护煤层(13-1煤层)卸压保护边界进行数值模拟分析,以数值分析结果为基础对被保护层边界范围内的煤岩及瓦斯动力参数现场测试,通过研究结果发现,在目前大规模运用底板穿层钻孔情况进行抽采的条件下,沿用的前苏联细则规定关于近水平煤层卸压角的数据偏保守。该研究结果能为类似近水平煤层条件下保护层开采确定被保护煤层的边界提供参考。
Abstract:
According to solid-fluid coupling theory,the pressure relief boundary of protected seam(Seam 13-1)for the 4th mining area of a mine under long distance condition was analysisted by numberical simulation.Based on the numerical simulation field test on coal petrologic parameters and gas dynamic parameters was carried.The results showed that the pressure relief angle of approximately horizontal seam based on former Soviet theory is smaller than the practical situation under the condition of large-scale crossing floor drilling.The research can provide references for similar condition.
