| 摘 要： | 在分析平顶山矿区水文地质背景和岩溶发育状况以及各岩溶含水层的水力联系基础上，引入岩溶致塌机理确立了岩溶塌陷的判定准则，得出了岩溶塌陷地区的疏干警戒水位公式，从定量上论证煤矿开采疏干排水是该区岩溶致塌的关键因素，当水位下降幅度达到2．52～8．03m时，平顶山七矿及附近区域容易产生岩溶塌陷，同时指出岩溶稳定系数K=1时，是临界危险警戒的地下水降深。

| Abstract: | Based on analyses of hydrogeological setting and karst development status in the Pingdingshan mining area as well as hydraulic relation between karstic aquifers, introduced mechanism of karstic caused collapse and determinate criterion of karstic collapses, worked out warning stage expressions of drainage in karstic collapsed zone. Quantitatively justified coalmine mining drainage is the key factor of karstic collapses. When fall in level extent is 2.52-8.03m, easy to cause karstic collapse in Pingdingshan No.7 coalmine and adjacent areas, meanwhile pointed out when karstic coefficient of stability K=1 is the critical warning stage of groundwater drawdown. |
