哈拉沟煤矿3^(-1)煤开采井下排水系统设计

Design of underground drainage system for 3^(-1) coal seam in Halagou mine

煤矿井下排水系统的优劣直接影响着矿井的安全。为了不影响矿井新水平正常接续生产,需要提前就井下排水系统进行设计。以哈拉沟煤矿为例,分析了3^(-1)煤水平延深开采时排水系统的设备选型、管路敷设及采空区储水工程的设计规划。

The underground drainage system directly affects the safety of coal mine. In order to keep the normal production of new level in Halagou coal mine,it is necessary to design the underground drainage system in advance. Taking Halagou coal mine as an example, the design plan of the drainage system such as equipment selection, pipeline laying and water storage project in goaf for the mining of 3-1 coal seam was analyzed.
