主井双向运输装卸载硐室改造施工工艺

Reconstruction Technology of Main Shaft Bidirectional Transport Loading and Unloading Chamber

花园煤矿采用主井实现固体物料自地面向井下高效运输,运煤运料联合运行。由于原先的装载硐室已不具备卸料的要求,因而主井装载硐室的改造施工成为解决充填开采的关键。花园煤矿采用分段施工方法,施工效果较好,经济效益明显。主井装载硐室的成功改造,为类似条件矿井矸石下井提供了重要的技术借鉴,对综合机械化固体充填开采的物料运输途径的发展具有重要意义。

Huayuan coal mine uses main shaft to realize efficient transport of solid material from groud to underground,and the combined operation of coal transportation and material transportation.Due to the original loading chamber can not meet the discharge requirements,the reconstruction of main shaft loading chamber has become the key to solve filling mining.Huayuan coal mine uses section construction method which has better construction effect and obvious economic benefits.The successful reconstruction of main shaft loading chamber provides important technical reference for gangue backfilling and has significance for the development of materials transportation ways of fully-mechanized soliod filling mining.
