摘要
在第四纪厚松散含水层下采煤，留设防水煤岩柱是预防顶板水的有效方法。本文从该项研究的现状及存在的问题出发，提出运用三维工程地质模型方法探讨导水裂隙带、含水层、隔水层、保护层的三维形态，进而通过空间分析并结合生产实际确定合理的防水煤岩柱尺寸，实现水体下煤炭资源的充分开发。
Pillar leaving is an efficacious method in preventing roof
water when mineslie under grave water bea ring layer of quaternary system. The paper,
beginning with the current situation and existing problems, presents the 3D engineering geology
model (3DEGM) to shape water transmitting fractured zone, water bearing layer, water resisting
layer and protective layer, and then analysis the connections among them finally, considering the
practice either, gains a rational height of safety pillar for avoiding roof water rush and fully
exploiting the coal resources beneath water body
