针对一些矿井瓦斯涌出量小但瓦斯灾害事故频繁的现状，结合义棠煤业公司实际情况，利用瓦斯地质理论，对局部煤层瓦斯异常涌出的原因进行了分析和研究，认为地质构造作用使地层受到揉皱破碎，致使顶板灰岩裂隙发育，大量游离态瓦斯贮存在裂隙中，当采掘活动扰动到这些裂隙时，游离态瓦斯集中释放造成局部瓦斯异常涌出，并据此提出了切实可行的瓦斯防治措施。
針對一些礦井瓦斯湧齣量小但瓦斯災害事故頻繁的現狀，結閤義棠煤業公司實際情況，利用瓦斯地質理論，對跼部煤層瓦斯異常湧齣的原因進行瞭分析和研究，認為地質構造作用使地層受到揉皺破碎，緻使頂闆灰巖裂隙髮育，大量遊離態瓦斯貯存在裂隙中，噹採掘活動擾動到這些裂隙時，遊離態瓦斯集中釋放造成跼部瓦斯異常湧齣，併據此提齣瞭切實可行的瓦斯防治措施。

In view of some small coal mines with low gas emission but frequent gas acci-dents,the gas geological theory was used to analyze and study the gas abnormal emission in local coal seams of Yitang Coal Industry Co.,Ltd..The results showed that the geological and tectonic action made the strata wrinkled and broken,leading to the development of roof limestone frac-tures.A large amount of free gas was stored in the fractures and then escaped when the fractures were disturbed by mining behavior,causing local gas abnormal emission.According to this fact, the practicable gas control measures were proposed.
