| 摘 要： | 为研究矿井的煤与瓦斯突出规律,以南山煤矿发生的192次煤与瓦斯突出(含动力现象)为事例,根据煤与瓦斯突出记录卡片,按突出的类型、标高和埋深、突出点地质情况、突出预兆、回采和掘进工作面突出发生情况,分类进行突出次数和百分比统计。分析得出南山煤矿煤与瓦斯突出规律以压出型居多;随着标高的降低、埋深的增大,突出发生的次数增多;地应力为矿井突出的主导因素,瓦斯压力和自重力为次要因素;突出诱因放炮占绝大部分;地质构造区域容易发生突出;绝大多数的突出事先都有突出预兆。

| Abstract: | In order to study the regularity of coal and gas outburst,in Nanshan coal mine 192 coal and gas outburst(including dynamic phenomena) as an example,according to the record card of coal and gas outburst,in the light of outburst type,elevation and depth,geological conditions,outburst omen,the occurrence of outburst stpoe and driving face,the classification statistics,the number and percentage of outbursting.Analysis of coal and gas outburst law in Nanshan coal mine mostly extrusion type.With the elevation of the lower,the depth increase,the growing number of outburst.Crustal stress is the main factor of mine outburst,the gas pressure and the self gravity as a secondary factor.The firecrackers comprised the vast bulk outburst incentive.Geological formations areas prone to outburst.The vast majority of the outstanding advance are omen. |
