顶板突(涌)水危险性“双图”评价技术与应用——以鄂尔多斯盆地西缘新上海一号煤矿为例

Technique based on “double maps” for assessment of water inrush from roof aquifer and its application——with New Shanghai No.1 coal mine at western edge of Ordos basin as example

摘要: 为解决煤层顶板突水预测预报评价难题，在提出了富水性指数和突水危险性指数的基础上，以鄂尔多斯盆地西缘新上海一号煤矿为研究对象，应用富水性指数和突水危险性指数的双图，对三个采煤工作面顶板突水危险性进行评价，结果表明，采煤活动位于富水区又位于突水危险区是顶板突（涌）水的充要条件。

Abstract: To solve the difficult problem of forecast and evaluation of water inrush from roof, on the basis of proposing the water abundance index and water inrush risk index, taking New Shanghai No.1 coal mine at western edge of Ordos basin as research object, the maps of water abundance index and and water inrush risk index were used to to evaluate water inrush risk from roof in 3 coal mining face. The results showed that coal mining at water-abundant zone and risky zone of water inrush was the necessary condition for water inrush from roof.
