覆岩离层注浆技术在济宁矿区的应用

Application of The Grounting Technilogy in Overburden Experiencing Bed Separation in Jining Mining Area.

济宁矿区是一个新矿区，煤炭储量丰富，自然环境优美，如何进行地表沉陷治理是一个重要的课题。本文通过总结济宁二号煤矿采用覆岩离层注浆技术治理地表沉陷的经验，证实了在济宁矿区使用覆岩离层注浆技术是可行的，并探索了离层发育规律，为下一步的注浆奠定了基础。

newly-developed Jining mining area is endowed with rich coal reserve and beautiful natural environment.Therefore control of ground subsidence becomes an important task.As evidenced by the experience gained at the Jining No.2 coal mine,it is feasible to control the ground subsidence through grouting the zone experiencing bed separation in the overburden.The paper also brings to light the law governing the development of bed separation,which is helpful to the application of the grouting technology in the future.
