Research on integrated mine goaf water prevention and control and exploring and releasing water anti jamming technology
Yuzhou Daliushan Coal Industry Co.,Ltd.,is based on Implementation Plan for Integration of Coal and Bauxite Resources in Henan Province,which integrates the resources of the original Yugou Second Mine New Well,Niejiagou West Well,and Shentong Coal Mine.With the mining activities of the surrounding Ⅱ1 coal seam,a certain scale of goaf was formed.Due to the wide distribution of old goaf and the presence of abandoned roadways,the possibility of local water accumulation cannot be ruled out.Therefore,Daliushan Coal Industry adopted a combination of surface transient electromagnetic and underground drilling methods to carry out work,but during the process of underground drilling,there was often a phenomenon of stuck drill during the period of drilling through the goaf,and accidents of drilling loss occured from time to time,leading to an extension of the drilling cycle and an increase in costs.After research and analy-sis by professional technical personnel in the mine,an anti jamming device was developed,which can effectively solve the occurrence of stuck drill and drilling loss accidents in rock fragmentation areas.This device also has a certain degree of anti deviation function,which improves drilling efficiency and ensures drilling construction quality,while saving drilling costs.
