摘　　要：在大量调研的基础上,结合丰城矿区内四对生产矿井现行的防治煤与瓦斯突出的现状,通过统计法,找出当前影响丰城矿务局煤与瓦斯突出的主要因素;利用工作面前方存在1～3 m的卸压范围,提出通过改变掘进工作面掘进方式,采用浅孔注水破煤代替爆破落煤,减小对煤体的震动以达到防治煤与瓦斯突出目的。采用现场测定数据分析、实验室测定与理论分析相结合的研究方法,找出浅孔注水破煤的安全技术参数。Based on the investigation, combined with the present status of coal and gas outburst prevention in four coal mines of Fengcheng mining area, the paper analyzed the main factors influencing coal and gas outburst in Fengcheng mining area. Using 1 - 3 m pressure relief range existed in the front of mining face, the paper proposed changing the tunneling excavation method, using shallow drilling water infusion instead of coal blasting to reduce the coal body vibration in order to achieve the purpose of coal and gas outburst prevention. Using the combined research methods of field measurement data analysis, laboratory test and theoretical analysis, the safety technical parameters of breaking coal technology of shallow drilling water infusion is found out.
