摘要
针对章村矿4225采区的复杂条件,通过异煤层采空区导水技术、综采工作面反复过纵横老巷、机头机尾带采等技术应用,成功将煤柱回收,并形成了一套成熟的应对多重叠加复杂条件的开采技术,为今后的各类工程积累宝贵的经验。
According to the complex conditions of Zhangcun Mine 4225 mining district, through the application of different coal seam goaf water fluid technology, mechanized mining face repeated crossbar old lane, the head and tail mining and other technologies, the coal pillar is successfully recovered and a mature mining technology to response to multiple superimposed and complex conditions is formed, accumulating valuable experience in all kinds of proiects for the future.
