岩溶裂隙承压水上采煤底板变形破坏规律与控制

Deformation-Failure Law and Control on Floor Affected by Mining above Pressurized Water in Karst Fissure

为了在岩溶裂隙承压含水层上安全采煤,针对陈四楼煤矿2513工作面的条件,采用理论分析与数值模拟相结合的方法,首先评价了2513工作面底板突水危险性。在此基础上,研究了底板注浆改造对采动底板破坏深度的影响规律。

In order to mine safely on the aquifer of karst fissure,evaluated the danger of floor water inrush in face 2513 using combined methods of theoretical analysis and numerical simulation based on 2513 face in Chensilou mine. The law of impact of bottom grouting on the damage depth of the floor.
