前言岩石与二氧化碳突出的防治措施,主要借鉴防治煤与瓦斯突出的一些经验和局部措施,如超前钻孔、卸压槽、水前冲孔等。由于种种原因,卸压槽、水力冲孔已先后停止使用;超前钻孔是目前唯一使用的局部措施。其作用是:1、预排一部分二氧化.碳降低气体压力;2、起部分卸压作用,但由于钻孔数目少、孔间变形很小,故卸压与降低气体压力作用也较小,对防突的有效性还有待进一步证实。从国内外防突经验来看,采用单一措施是不行的, Preface Rock and carbon dioxide prevention and control measures, mainly learn from the prevention and control of coal and gas outburst of some experience and local measures, such as advance drilling, pressure relief trough, water before punching. Due to various reasons, the pressure relief tank, hydraulic punching has been discontinued; advanced drilling is the only local measures. Its role is as follows: 1. Part of the pre-emission of carbon dioxide. Carbon to reduce gas pressure; 2. Part of the relief from pressure, but due to the small number of holes, holes deformation is very small, so the pressure relief and reduce gas pressure is also small, The effectiveness of the anti-sudden remains to be further confirmed. Outbreak prevention experience at home and abroad point of view, the use of a single measure is not acceptable,
