Study Of Prevention System For Coal Bump At Deep Mining In Kailuan Coal Mining Area

Based on the occurrence law of coal bumps, the main factors of coal bumps inKailuan Mining District are investigated, which are including depths and coefficient oflateral pressure. The multistage coal bumps prediction and control technology system ofthe Kailuan Mining Area is built with the characteristics of information mutual feedbackand continuous optimization mechanism, which is in the light of accumulatedexperience of coal bumps prevention and the advanced prediction and controltechniques of coal bumps both at home and abroad. According to the actual geologicalstructure and minging condition of Kailuan Mining Area, the coal bumps prevention andcontrol technology are put into effect, and based on the implementation effect feedbackthe optimization of technical measures are carried out at the same time, including thereasonable choice of mining method, the mining protective coal seam, the local pressurerelief measures and the strengthening of supporting measures, which can weaken oreliminate the power source and the of coal bumps occurrence and improve the localstress environment.
