Surrounding Rock Monitoring Technology in Single Special Thickness Coal Seam

Taking the single special thickness seam in Binchang mining area as the background,through on-site industrial practice method and the displacement monitoring by deep stope basis points in working face,the dynamic displacement of roadway two sides and the roof are determined under the influence of mining,which is took as basis to judge the separation situations of roadway surrounding rock,and timely detect potential safety hazard to provide the basis for controlling the surrounding rock stability and safeguarding coal mine safety production.Meanwhile,this paper studies the bolt and anchor cable force measurement,and analyzes the stress state of the bolt and cable to determine the safety of the bolt and cable support.Timely found the problems of bolt and cable support and improve the supporting effect.
