大硐室支护参数优化及快速施工技术研究

Study on Optimization of Support Parameters of Large Chamber and Rapid Construction Technology

针对国内在大硐室施工方面存在施工速度慢及支护困难等技术难题,通过王庄煤矿井下1号换装硐室100m2硐室对支护参数优化,以解决在大硐室施工速度慢的问题,保证了王庄煤矿超大1号换装硐室在计划施工天数内安全顺利投入使用,同时也为同类型大硐室施工起到借鉴与指导作用。

Aiming at the large chamber construction is construction speed is slow and difficult technical problem of branch support.The 100m2 chamber No.1 Wangzhuang coal mine underground reloading of support parameter optimization.In order to solve the problem of slow speed in construction of large chamber.The Wangzhuang coal mine large No.1 reloading chamber in the planned construction of safely and successfully put into use.At the same time as the construction of the same type of big cham-ber to use for reference and guidance.
