三家子矿煤层瓦斯赋存及涌出规律研究
|
摘要
矿井瓦斯历来是煤矿安全工作的重点,随着矿井开采深度的增加及开采强度的加大,矿井的瓦斯涌出量也越来越大,在某些矿井的某些地点发生瓦斯突出,严重影响煤矿安全生产。
论文结合三家子煤矿的实际条件,分析了影响矿井瓦斯含量的因素,通过矿井瓦斯参数现场测试和实验室测试,确定了矿井的瓦斯含量、瓦斯压力、透气性系数,瓦斯衰减系数等参数。利用最小二乘法进行回归分析,研究了矿井深部瓦斯赋存规律,绘制出矿井瓦斯涌出量等值线图。运用板块构造理论和区域构造演化理论,分析矿井地质构造,结合以往相关瓦斯数据以及瓦斯涌出量分布图相关数据,研究了矿井深部瓦斯涌出规律,最后对矿井深部进行了煤与瓦斯突出区域预测,划分出煤与瓦斯突出的危险区域。
通过三家子矿实例研究表明:凸型区域构造不利于瓦斯的保存,凹型区域构造有利于瓦斯的保存。三家子矿海陆过渡相沉积环境、以泥岩、砂泥岩为主体的围岩、北东向扭性逆断层为主体的构造环境造就了三家子矿高瓦斯的现状,指出地质构造是三家子矿煤与瓦斯突出发生的背景,三家子矿六组煤瓦斯压力呈不均匀分布,东一采区和西一采区瓦斯压力相差较大,-700m水平西二区-610石门、-660石门,-700m水平西一区650石门,-700m水平东一区-700石门,-700m水平东二区-700石门是区域预测的危险区。
Methane gas is always the key of coal mine safety, with the mine’s depth and intensity enhancing, there is more and more methane flowing out, coal and gas outburst happens somewhere in the coal mines which have serious influence on coal mine safety.
The paper based on the actual conditions of SanJiazi coal mine, analyzes the factors which affect the contents of coal mine methane gas, confirms gas quantity, gas pressure, gas through coefficient, attenuation coefficient by laboratory tests and field tests of the gas parameters, uses the Least-Squares regression analysis studying gas distribution orderliness in deep of coal, draws gas flood map, exerts paleoplate tectonic theory and region geologic structure evolvement theory, analyzes the geo-structure of the mine, combines with the former relative gas data and gas flow-volume distribution map, studies the gas emission law in the deep of the mine, makes the prediction of coal and gas outburst and divides the dangerous area of coal and gas outburst.
Research indicates that convex structures are not good for preservation of gas but concave structures are just the opposite. The deposits of the transitional nature from marine to continental facies, mudstone-sand shale based wall rock, NE shear reverse faults based tectonic setting and igneous rock decides the high gas content of SanJiazi coal mine. The paper points out that the geo-structure is the background of coal and gas outburst in SanJiazi coal mine. Gas pressure of coal group six distributes unevenly, gas pressure of area west one and area east one differ a lot. -700m level area west two -610 crosscut -660 crosscut, -700m level area west one -650 crosscut, -700m level area east one -700 crosscut, -700m level area east two -700 crosscut are dangerous areas of regional prediction.
