疏放煤矿采空区积水方案优化设计

Hydrophobic Gob Water of Luoling Coal Main Scheme Optimization Design of Beisu Coal Mine

煤矿闭坑前曾多次违规开采与相邻煤矿之间的井田边界隔离煤柱,造成多处煤柱宽度变窄,裂隙发育,破坏了煤体的完整性。该矿排水设施撤出后,不断增加的采空区积水致使水位上升、水压增大,给煤矿安全生产带来隐患。

Before coal mine elosing, which had been an illegal mining boundary isolated coal pillar between with adjacent coal mine, causing several pillars width narrow, crack development, undermines the integrity of the coal. After the mine drainage is withdrawn, the increasing of gob water led to rising water levels, increase water pressure, bring hidden trouble for Beisu coal mine production safety.
