    Prevention Study on Mining Dangerous Zone With Weak Outburst Proneness and Complicated Conditions

    • For the rock burst problem caused by complex geological conditions, stress concentration of section coal pillar, we firstly study rock burst proneness test of No.3 coal seam, draw the conclusion that No.3 coal seam has weak outburst proneness, and so does the roof strata; the positive correlation of bursting proneness indexes between coal samples and coal rock composition samples is qualitatively obtained. Secondly, we divide rock burst dangerous zone in where drilling bits and electromagnetic radiation monitoring is applied, coal face existing hazard of rockburst when it passing through fault and mining normally. Finally, prevention measures on pressure releasing of deep hole blasting, supporting roadway with 4.1 m narrow pillar are proposed, and safety production is ensured.
