淮南潘谢矿区矿井安全改建及水平延深开采方案设计

Mining scheme design of safety reconstruction and horizontal extension in Pan-Xie mining area of Huainan

为了保证淮南潘谢矿区多个矿井可持续开采,基于矿区表土层厚、煤层多、煤层埋藏深、瓦斯含量高、透气性差、地压大的地质特征,以充分利用资源为目标,在现有的生产系统上,统筹分析给出了矿区矿井延深方式、块段及采区划分、各煤层(组)瓦斯治理模式、防治水方案以及采区系统巷道布置等设计原则,形成了一套适用于复杂地质条件下高瓦斯突出煤层群开采的矿区矿井安全改建及水平延深的设计方法,为类似矿井安全改造和水平延深提供参考。

In order to ensure the sustainable exploitation of coal mines in Pan-Xie area of Huainan,based on the geological characteristics of the mining area with thick topsoil layer,multiple coal seams,large coal seam burial depth,high gas content,poor permeability and large ground pressure,combined with the current mining area succession of the mine and the existing production system,some design philosophy of mining scheme are analyzed to make full use of resources,such as the way of extending depth,division of Mining area and working sector,control mode of coal seam(group)gas,program of groundwater disaster control,and roadway system layout of mining area.Design methods were summarized for safety reconstruction and horizontal extension for coal mines in high gas outburst coal seam under complex geological conditions.The study can provide reference for safety reconstruction and horizontal extension of coal mine with similar conditions.
