安全高效生产是煤矿工作的重中之重,整理分析了大平煤矿历年的煤与瓦斯突出资料,总结出了煤与瓦斯突出的基本特征。运用瓦斯地质理论分析了影响大平煤矿煤与瓦斯突出的主要因素为地质构造、高能瓦斯、煤层埋深以及构造煤,尤其是褶皱和断裂构造及高能瓦斯赋存。认为地质构造通过控制瓦斯赋存、煤体结构类型来控制突出的发生,是发生突出的主导因素;高能瓦斯作为突出发生的能量条件,是影响突出的重要原因;而大平煤矿煤层埋深与煤层瓦斯含量和瓦斯压力关系明显,瓦斯垂直分带性强,是煤与瓦斯突出的另一个原因;同时大平煤矿构造煤成层发育,属易突出煤层,为煤与瓦斯突出创造了物质条件,是该矿发生煤与瓦斯突出的关键因素。这些原因为今后防治煤与瓦斯突出工作指明了方向。
Safe and efficient production is the most important task in coal mines. The data of coal and gas outburst in Daping Coal Mine have been analyzed and summarized, and the basic characteristics of coal and gas outburst have been summarized. The main factors that influence the coal and gas outburst in Daping Coal Mine are analyzed by using gas geological theory as geologic structure, high-energy gas, coal seam depth, tectonic coal, especially fold and fault structure and high-energy gas occurrence. It is considered that the geological structure plays an important role in controlling the occurrence of salient by controlling the occurrence of gas and the type of the structure of the coal body. High-energy gas is an important factor that has an outstanding impact on energy conditions. However, The relationship between gas content and gas pressure is obvious. Gas vertical zonation is another reason for the outburst of coal and gas. At the same time, the structural coal of Daping Coal Mine is stratified and developed, which is a kind of easily outburst coal seam. It creates material conditions for coal and gas outburst and is The coal and gas outbreak occurred in the key factors. These reasons point out the direction of prevention and control of coal and gas outburst in the future.
