摘　　要：通过收集分析贵州矿区381对矿井、695层煤的突出指标和以往120对矿井发生的214起典型煤与瓦斯突出事故,对贵州矿区煤与瓦斯突出指标分布特点及突出特征进行了研究,提出了针对性的防突措施:加大煤层突出指标的测试工作,对黔北、织纳、六枝、盘江、水城等突出强度大和突出次数多的矿区制定严格的管理制度,加大煤巷掘进工作面的防突工作,并加强放炮管理、动力现象监测和地质构造探测,以此减少贵州矿区煤与瓦斯突出事故。With collection and analysis of outburst indexs in 381 mines and 695 seams and 214 coal and gas outburst accidents occurred in 120 mines in Guizhou mining areas,a study on coal and gas outburst index distribution features and outburst features in Guizhou mining areas was conducted,and relative outburst prevention countermeasures were proposed.Enhanced coal seam outburst index measurement,developing strict management system to mining areas with high outburst strength and more outburst such as Qianbei,Zhina,Liuzhi,Panjiang and Shuicheng,enhanced outburst prevention work of coal roadway heading face,and enhanced blasting management,dynamic phenomenon monitoring and geological structure detecting could be applied to reduce coal and gas outburst accidents occurred in Guizhou mining areas.
