| 摘 要： | 为调查并评价新疆阜康矿区白杨河西煤层气的资源潜力和可采性,在白杨河西一带布设了煤层气小井网。通过对该区地形地质条件和煤层气储层特征的分析,结合国内其它地区小井网布设的经验,确定采用"W"型布设井网,并确定了井间距,以期对今后本区煤层气勘查有所借鉴。

| Abstract: | Based on the experimental study on the coal spontaneous combustion characteristics of Ningtiaota coal mine,the spontaneous combustion period and characteristics were analyzed and predicted.The experiment results show that the period of spontaneous combustion is 34 days,the critical temperature is 75-85℃,the dry temperature is 90~120℃ and the spontaneous combustion cannot happen in nature if the thickness of the remained coal is less than 0.5m. |

| Keywords: | spontaneous combustion characteristic experimental prediction limit parameters of spontaneous combustion |
