综采工作面悬顶处理技术研究

Study on Suspended Roof Treatment Technology at Fully Mechanized Face

综采工作面实施深孔预裂爆破强制放顶,提高了爆破效果,大幅度降低了初次来压强度和初次来压形成飓风的可能性,减小了对工作面人员、设备、通风设施的威胁与破坏,达到了综采面安全回采的目的。

The forced roof caving with deep - hole presplitting blasting was implemented at the fully mechanized face. The blasting effect was greatly increased. The intensity of the first pressure and the possibility of forming wind were significantly reduced. The threats and destruction of persons and equipments etc. were reduced. The purpose of safe mining at the fully mechanized face was achieved.
