综采工作面过地质构造异常带注浆加固技术

赵庄二号2309综放工作面内地质构造异常带大量发育,导致工作面煤岩体结构破碎,对工作面的顶板管理及瓦斯治理带来困难,威胁工作面的回采安全。为解决这一问题,针对2309综放工作面地质构造异常区域采取注浆加固措施,并对各加固区分别进行注浆加固方案设计,并对注浆加固效果进行监测分析,科学合理地解决工作面过地质构造异常带的安全问题,为工作面的安全生产提供保障。

Grouting reinforcement technology for abnormal geological structure in fully mechanized mining face

Zhaozhuang No.22309 fully mechanized caving face geologic al structure abnormal zone developed in large quantities,resulting in the coal and rock structure of the working face broken,the working face roof management and gas control brought difficulties,threatening the mining safety of the working face.To solve this problem,in view of the geological structure of full-mechanized caving mining face 2309 abnormal region by grouting reinforcement measures,and the grouting reinforcement scheme design with the reinforced area respectively,and the reinforcement effect of the grouting monitoring analysis,scientific and reasonable to solve the problem of face of tectonic migration of safety,provide safeguard for safety production of working face.
