煤矿封闭采空区瓦斯发电气源储量预测方法研究
|
摘要
为解决山西省重点工程高河煤矿乏风氧化发电项目瓦斯气源不足问题,提出了通过抽采已封闭采空区瓦斯,用以补充气源的方案,探讨了各类采空区瓦斯储量的计算方法及可利用性的评估方法。研究结果表明:高河煤矿W1303和W1305采空区瓦斯储量分别为508 508 m~3和1 163 879 m~3,抽采可持续性较强,而E1302采空区瓦斯储量仅为105 147 m~3,储量少,抽采时间短,可持续性较差,此采空区压斯预计抽采时间能够达到一年,但半年后有新的采空区可以接替,从而实现采空区抽采的持续性。此方法对瓦斯发电工程前期投资中瓦斯可利用性评估具有重要指导意义。
In order to solve the gas source shortage problem of a mine ventilation gas oxidized power generation project in Gaohe Mine of Shanxi Provincial Key Project,a plan to drain the mine gas from the closed goaf to replenish the gas resources was provided and a discussion was conducted on the calculation method and the availability evaluation method of the mine gas reserves in different goaf.The study results showed that the mine gas reserves in Goaf W1303 and W1305 of Gaohe Mine was 508 508 m~3 and 1 163 879 m~3 individually.The sustainability of the gas drainage was high.But the mine gas reserves in Goaf E1302 was 105 147 m~3,the gas reserves was low,the gas drainage time was short and the sustainability was poor.The expected gas drainage time could be a year.After a half year of the gas drainage,there would be a new goaf to be replaced.Therefore,the sustainability of the gas drainage from the goaf could be realized.The method would have important guide significances to the evaluation of the mine gas availability in the initial investment of the gas power generation.
