摘　　要：针对我国煤与瓦斯突出矿井采掘接替紧张的现状和煤矿安全监察工作的需要,提出了煤与瓦斯突出矿井安全煤量概念,研究探讨了安全煤量与"三量"之间的相互关系,结果表明:安全煤量属于准备煤量的一部分,它是指煤与瓦斯突出矿井准备煤量范围内已无突出危险的煤量,安全煤量必须有足够的可采期.为确保回采安全,回采煤量必须是安全煤量.突出矿井采取保护层开采结合被保护层卸压瓦斯抽采技术和预抽煤层瓦斯技术获得足够的安全煤量.通过对淮北祁南煤矿"三量"和安全煤量的分析得出,祁南煤矿的安全煤量占到准备煤量的五分之四,为回采煤量的2.3倍,准备煤量、安全煤量和回采煤量可采期分别为16.6,13.3,5.9个月.矿井的生产实践表明,祁南煤矿安全煤量可以满足矿井的正常接替和安全生产需要.The concept of the amount of safely mineable coal was proposed to help with safety supervision during excavation in mines susceptible to coal and gas outburst. Relationships between the amount of safely mineable coal and ＂three coal reserves＂ were studied. The results show that the amount of safely mineable coal is the non-outburst coal quantity in preparatory coal quantity and that it must have enough of a production period. For safe mining the quantity of mined coal must be less than the amount of safely mineable coal. This safely mineable coal includes about four fifths of the preparatory coal quantity and 2.3 times the mining coal quantity. The mineable periods of preparatory coal quantity, safety coal quantity and mining coal quantity are 16.6, 13.3 and 5.9 months, respectively. The practice at the Qinan mine is such that the amount of safely removable coal meets the requirements for normal relay and mining safety.
