黑龙江省矿井瓦斯抽放利用前景评价

黑龙江鸡西、鹤岗、双鸭山和七台河4大主要矿区有矿井42个,其中70%都是高瓦斯矿井。现已经有8个矿井报废,在2005年以前还有5个矿井陆续报废。矿井报废后,其煤层及巷道中蕴藏着大量的瓦斯并不断地向外泄漏,影响当地的环境及污染大气。文章通过对各矿区瓦斯抽放和报废矿井情况的分析,提出了在黑龙江省进行矿井瓦斯抽放利用,具有广阔的市场前景。

Evaluation on Prospects of Coal Mine Methane Drainage and Utilization in Heilongjiang Province

There are 42 mine wells in four major mine areas,Jixi, Hegang, Shuangyashan and Qitaihe, in Heilongjiang province, China , 70 % of which are high gas mine wells. Eight wells have been abandoned so far, and another five wells will be sequentially abandoned by the year 2005. With the wells abandoned, large amount of gas remaining in the coal seams and tunnels keep leaking to the outside, severely influencing the local environment and polluting the atmosphere. In this paper, the analysis on the conditions of gas draiuage and abandoned wells in each mine area shows the bright market prospects for gas drainage and utilization in mine wells in Heilongjiang province.
