摘要
结合斜沟矿18110作业面工程实际,对大采高综采面末采期顶板管理展开探究,在分析18110作业面矿压显现规律的基础上,通过煤体预注固安特加固、挂网工艺优化等措施,有效解决了18110综采面末采时顶板管理难度大、安全事故多发的难题,为生产作业安全提供了有力保障。
Combined with engineering practice of 18110 work face in Xiegou Coal Mine, this paper studied roof management at the mining end in fully mechanized face with large mining height, analyzed mine pressure behavior of 18110 workface. Problems such as difficult roof management and multiple safety accidents were effectively solved by measures of reinforceing coal-body by pregrouting Guante and hanging net technology optimization, which provided a powerful guarantee for production safety.
