摘要
本文在结合承压水上采煤的实践和参考煤炭工业部《矿井水文地质规程》的基础上，进行了详细的理论分析，提出了断层上下盘及其陷落柱合理防水煤柱尺寸的计算理论公式。以太原市东山煤矿为例，给出了不同开采水平的构造防水煤柱的合理尺寸，并用于带压开采设计。
Abstract Based on a
combination of mining practice over underlying pressurized water and Mining Hydro-Geological
Regulations issued by the former Coal Mining Ministry, detailed theoretical analysis was
conducted. A theoretical formula for calculating a reasonable size of water prevention coal pillar
for both a hanging wall and footwall of a fault was put forward. A case study based on Dong San
Colliery was carried out and the rational sizes of structural water prevention coal pillars for
different mining level were derived and brought into practice in a design of mining with pressure.
