花山煤矿大倾角大采高综采工作面过旧巷技术

6143工作面是花山煤矿大倾角大采高综采面，开采难度大，地质条件复杂。为保证综采工作面安全开采，通过工作面开采前，对周边小窑进行调查，编制探放水设计，完善相关预案和技术措施，工作面揭露旧巷后，及时对旧巷进行维护、加强通风管理等技术管理，排除了施工过程中可能遇到的水、顶板及有毒有害气体等隐患，保证了6143大倾角大采高综采面安全通过旧巷。通过本次实践，总结许多宝贵经验，为今后综采工作面过旧巷提供技术依据。

Technical Practice of Passing the Old Roadway in the Fully Mechanized Mining Face with Large Dip Angle and Large Mining Height in Huashan Coal Mine

The 6143 working face is a fully mechanized mining face with large inclination and high mining height in Huashan Coal Mine,which is difficult to mine and has complicated geological conditions.In order to ensure the safe mining of the fully mechanized mining face,before the mining of the working face,survey the surrounding small kiln,prepare the design of water exploration and discharge,and improve the relevant plans and technical measures.Technical management,such as management,eliminates hidden dangers such as water,roof and toxic and harmful gases that may be encountered during the construction process,ensuring that the 6143 high inclined and high mining fully mechanized mining face safely passes the old lane.Through this practice,a lot of valuable experience is summarized to provide a technical basis for the future comprehensive mining working face to pass the old lane.
