煤层安全承压开采研究——以赵庄二号井3号煤层为例

Study on Safe Pressure Mining of Coal Seams——Taking No.3 Coal Seam of Zhaozhuang No.2 Well as an Example

山西晋煤集团赵庄二号井目前主采的二叠系山西组下部3号煤层存在承压开采问题。评价了3号煤层底板石炭系太原组、奥陶系马家沟组灰岩水对矿井充水的影响,为实现矿井安全承压开采及防治提供了可靠的依据。

At present, the pressure mining problem exists in No.3 coal seam of lower Permian Shanxi Formation in Zhaozhuang No.2 well of Shanxi Jincheng Anthracite Mining Group. This paper evaluated the influence of limestone water in Carboniferous Taiyuan Formation and Ordovician Majiagou Formation of No.3 coal seam floor on mine water filling, which provides a reliable basis for realizing safe pressure mining and prevention.
