高应力软岩采场半封闭支护工艺的实践

Practice and improve of the prop up technology half-seal in the mining-space of soft rock in high stress zone

总结并分析了小官庄铁矿两次半封闭支护实践的经验和技术数据 ,应用非弹性变形区理论对半封闭工艺的支护机理和支护参数进行论证 ,并提出了新的改进方案。

This paper analyzes two times experience and technology data of the experiments in Xiaoguanzhuang iron mine half closed propping up. The theory of elasticity deformation zone is applied to illustrate the mechanism of half closed prop up technology principle and prop up data. A new improving scheme is put forward at last.
