摘要
2014年第四季度停产期间,采用了有效的工作面设备、顶板及采空区管理技术。针对顶板压力变大,采高变低和采空区煤炭氧化自燃问题,采取"小推进"和"大推进"相结合的治理措施,成功实现了工作面在停产期间的安全过渡。
Effective mining face equipment along with the management technology of roof and goaf were established during the production halt of the fourth quarter in 2014. On the issue of roof pressure becoming larger,mining height becoming lower and coal spontaneous of the mined-out regions,'small push 'and 'great advace'were combined. As a result the safety transition of mining face during the production halt was successfully achieved.
