摘要
采空区充填开采为"三下"煤炭的合理开采创造了条件.本文结合现场地质条件,分析了采空区全部充填条件下,充填体压缩率对上覆岩层活动的影响规律,分析了该条件下关键层的稳定性及其对上覆岩层活动的影响,提出了保持岩层移动在合理范围的充填体允许压缩率.研究结果可为采空区充填开采的有效实施提供参考.
The mining with filling in goaf provides advantages for the rational mining of coal under buildings, railroads and water bodies. Based on field geological conditions, this paper analyzes the influence law of the bulk factor of filling body on the overlaying strata movement, the stability of key strata and its influence on the overlaying strata movement under the condition of complete fill in goaf, and puts forward the allowable bulk factor of filling body of sustaining strata movement in the rational range. The research results has provided references for the effective execution of mining with filling in goaf.
