摘　　要：在采空积水区下采煤的防水煤岩柱设计关系到矿井的安全生产和资源开发的合理性,需要在一定的理论指导下完成。文章以新兴煤矿的延深设计为例,通过分析覆岩破坏规律,分别计算冒落带、裂隙带的最大高度和保护层高度,最终确定以+150^+180 m水平之间煤岩柱作为防水煤岩柱,并采取必要的开采技术措施,为±0m水平的安全开采提供了可靠的科学依据。Stagnant water in the mined - out area of coal mining under the waterproof design bearing rock mine production safety and resource development is reasonable, it is completed under the guidance of the theory. Taking the extension design in Xinxing Coal Mine as an example, by analyzing the destruction of cover rock, calculating the height of roof failing zone, fracture zone and protective layer, finally the coal rock pillar in the ＋ 150- ＋ 180 m level, is taken as the waterproof coal rock pillar. The essential mining technical measure is adopted. The reliable scientific basis is provided for ±0 m level safe mining.
