国投新登煤业31采区北翼瓦斯赋存规律研究

国投新登煤业前期采掘过程中矿井瓦斯涌出量较低,但随着开采深度的增加,瓦斯含量及压力具有明显上升的趋势,矿井迫切需要搞清深部区域的瓦斯赋存规律.结合矿井实际情况针对这一问题进行了研究,分析了影响深部区域瓦斯涌出的各种因素；研究了煤层瓦斯含量与埋藏深度的关系,绘制了31采区北翼的瓦斯含量等值线图；结合《防治煤与瓦斯突出规定》对该区的瓦斯突出危险程度进行了评价,划分出了突出危险区,并给出了防治煤与瓦斯突出的技术措施.现场生产表明,研究结果符合矿井实际情况,对矿井安全生产具有一定的指导意义.

Study on the law about gas occurrence in 31 mining area north wing about Xindeng coal mine of the national investment and development company limited

The mine gas emission rate is low in the early stage of the mining process in the national investment and development Co. , Ltd. But with the increase of mining depth, gas content and pressure have significant upward trend, the coal mine need to find out the gas occurrence law of deep area urgently. Combining with the actual situation of coal mine, this paper carries out the research on this problem. This paper analyzes the various factors that influence gas emission in deep area, discusses the relationship between gas content and buried depth, draws the gas content isoline graph in north wing of 31 mining area. On the basis of coal and gas outburst prevention regulations, the paper evaluates the degree of gas outburst danger, divides the outburst dangerous area, and provides the technical measures that prevent coal and gas outburst. The field productions show that the results are consistent with the actual situation of coal mine and have certain guiding significance for coal mine safety production.
