青东煤矿7#煤层构造煤分布规律及其控制因素

为研究构造煤对煤与瓦斯突出的控制作用，通过解译钻孔测井曲线，结合现场揭露情况，对7#煤各钻孔构造煤厚度进行了判识，并利用软件Surfer8绘制了7#煤构造煤厚度等值线图，在此基础上对7#煤构造煤分布特征及控制因素进行了分析。结果表明：7#煤构造煤普遍发育，东部构造区较为发育，且构造煤厚度变化较大；中部构造区，构造煤厚度分布稳定；在西部构造煤在向斜核部较发育，两翼相对变小。井田构造分布受褶曲构造和断裂构造的影响。

Qingdong coal mine 7# coal seam structure coal distribution laws and its controlling factors

Aimed at identifying the control effect of tectonic coal distribution on coal and gas out- burst, this paper identifies the thickness of tectonic coal found in 7# coal seam structure by interpreting borehole logging curve and combined with field investigation and offers contour map of tectonic coal thick- ness in 7# coal seam structure, developed by using software Surfer 8 and gives an analysis of tectonic coal distribution of 7# coal seam. The results shove that tectonic coal in 7# coal seam is found to be generally developed; eastern tectonic zone is better developed, with a greater variation in tectonic coal thickness; central tectonic zone has the stable distribution of tectonic coal thickness; and western tectonic zone is marked by relatively developed syncline core, with the two wings staying relatively smaller. Ida structure distribution is subjected to folding structure, faults and ground stress factors.
