覆岩破坏特点和观测原理

Characteristics and observation principle of overburden failure

目前,为了保证工作面回采安全,众多学者付出了很多努力。为更高效开采煤层,释放水体下压煤越来越受到各界专家的关注,覆岩破坏规律的研究成为研究的核心问题。网络并行电法、地电场观测、电极电流反演技术是覆岩破坏观测的三个主要的方法。研究覆岩的破坏特点和岩石的观测原理具有十分重要的意义,对煤层开采具有重要的参考价值。

At present,in order to ensure the safety of mining face,many scholars have made a lot of efforts.For the more efficient mining of coal seam,the release of coal pressure under water is more and more concerned by experts from all walks of life,and the study of overburden failure law has become the core problem of the research.Network parallel electric method,ground electric field observation and electrode current inversion are three main methods for overburden failure observation.It is very important to study the failure characteristics of overburden and the observation principle of rock.It has important reference value for coal seam mining.
