Study on Effect Evaluation of Protective Seam Mining

LIU Ming-ju1,WANG Mian1,LI Bo2,HU Shou-tao1(1.Research Center of Mine Safety Engineering and Technology,Henan Polytechnic University,Jiaozuo 454003,China; 2.School of Resources and Safety Engineering,China University of Mining and Technology(Beijing),Beijing 100083,China)  
According to the gas control measures made for the protective seam mining in Jinling Mine,based on the mine geological gas exploration information,the paper discussed the rationality of the protective seam mining.The paper introduced the mining method for the below protective seam and the gas drainage method with boreholes through the floor strata and evaluated the effect of the protective seam mining.The results showed that after the mining measures made in the protective seam of the high gassy mine,the seam pressure would be released and great cracking would be occurred in the seam.The max gas content value and the max gas pressure would be all reduced below the critical values individually as 8.00 m3/t and 0.74 MPa.Thus the seam gas deposit law would be changed,the seam permeability would be improved,the gas drainage effect would be improved and the coal and gas outburst danger would be highly reduced.
