摘　　要：为了获得南庄煤矿12号、15号煤层瓦斯地质规律及其突出危险区域,通过井下瓦斯含量直接测定法,运用地质构造控制理论分析了12号、15号煤层瓦斯赋存特征及其影响因素,得到了埋藏深度是影响12号、15号煤层瓦斯含量变化的主要因素,煤层围岩对瓦斯有保存作用,断层等因素对局部瓦斯含量变化有所影响,褶皱没有影响等结论。在此基础上对12号、15号煤层突出危险区进行划分,结果为该矿井12号、15号煤层埋藏深度分别大于160 m、470 m的区域均为突出危险区,这对防治瓦斯突出和保证矿井的安全生产具有重大意义。In order to obtain No. 12 and No. 15 Coal Seam gas geology law and highlight the danger zone in Nanzhuang Coal Mine through downhole gas content t,it analyze No. 12 and No. 15 Coal Mine gas occurrence characteristics and its influencing factors by using the geological structure control theory. The buried depth is affected No. 12 and No. 15 Coal Seam content variation the main factors, the coal seam surrounding rock protect gas, fault and other factors have an effect on the local gas content change, fold does not affect the conclusion. It made division on the basis of No. 12 and No. 15 Coal Seam outburst danger zone ,the results is that buried depth of No. 12 and No. 15 Coal Seam is more than 160 m and 470 m area are respectively highlight the danger zone,it is of great significance that the gas outburst prevention and control and ensuring mine safety in production.
