断层带岩体一直是煤炭开采过程中受关注的区域。随着能源紧缺问题的进一步突出,煤柱也日益成为被关注的主要区域。利用FLAC-2D数值模拟软件对断层带开采对底板和断层切割的含水层的岩体的应力和位移的变化进行模拟分析,提出了断层煤柱留设的建议,为科学留设防水煤柱提供依据。
Fault zone rock mass has been a concern in the coal mining process. With the energy shortage further highlighted, coal pillar is also increasingly becoming the main area of concern. The FLAC-2D numerical simulation software was used to simulate and analyze the changes of stress and displacement of the rock mass in floor and fault cut aquifers in the mining of fault zone. Proposed to leave the fault pillars, in accordance with.
