李一矿-660m东翼采区在高水位灰岩水下开采可行性研究

Researches on the feasibility ofthe extraction of the eastern m ine area LiyiMine on the condition ofhigh levellim estone w ater at - 660m under ground

主要通过水文地质特征分析，从采区涌水量、临界水头值及临界隔水层厚度及相关的水文地质因素对李一矿－ ６６０ ｍ 水平东翼采区在高水位灰岩水威胁下开采的可行性进行了研究。

Through the analysis of hydrological yeology's features by analyzing the gielding waterofm ining section, thecriticalvalueofw aterhead, the criticalthicknessof water-resisting layer and othrhydrologicalgeology factorsconcerned, the researches on the feasibility ofthe extraction ofeastern m ine area LiyiMine at- 660m underground with the m enance ofhigh-levellim estone w ater have been done.
