影响邹庄煤矿7_2煤层瓦斯赋存的因素

The Factors Influencing on 7_2 Coal Seam Gas Occurrence in Zouzhuang Coal Mine

邹庄煤矿为宿县矿区新建矿井,32煤层为即将开采煤层,72煤层为下一开采煤层。72煤层受岩浆岩侵蚀严重,且埋深较32煤层深,因此72煤层的瓦斯赋存情况更加复杂。文章系统分析影响瓦斯赋存的因素,采用灰色关联方法,对影响72煤层瓦斯含量的各个因素进行研究,建立了灰色关联模型,并计算出了各项因素的关联度。研究结果表明:影响邹庄煤矿72煤层瓦斯赋存的主要因素为煤的灰分、煤层埋藏深度、地层厚度、挥发分、煤厚与地层厚度比等,利用多元回归的分析方法对邹庄煤矿72煤层的瓦斯含量进行预测,并为其以后的安全开采提供前瞻性预测数据。

Zouzhuang Coal Mine is new mine of mining area in Suxian County,tbe 32 Coal Seam is about to mining,the 72 Coal Seam is the next one. The 72 Coal Seam affected by the erosion of magmatic rocks,and buried more depth than 32 Coal Seam,so 72 Coal Seam gas occurrence situation is more complicated. This paper made system analysis of the gas occurrence influencing factors,adopt the grey correlation method,made analysis of the various factors influencing the 72 Coal Seam gas content,the grey correlation model was established,and calculated the correlation of various factors. The research results show that the main factors impact gas occurrence were the coal ash,coal seam buried depth,formation thickness,volatile,coal thickness and formation thickness ratio of 72 Coal Seam in Zouzhuang Coal Mine,using multiple regression analysis method to predict gas content 72 Coal Seam in Zouzhuang Coal Mine,and offers prospective forecast data mining for their future security.
