基于测井曲线的煤体结构判别技术——以袁店一井煤矿105采区为例

Coal Structure Discrimination Technology Based on Logging Curves—Taking the 105 Mining Area of Yuandian No. 1 Coal Mine as an Example

摘要: 在我国淮北矿区，复杂地质条件致使煤矿瓦斯突出灾害频发，严重威胁安全生产。研究表明，煤与瓦斯突出多发生于构造煤发育区域。本文基于构造煤和原生煤在物理结构与化学性质方面的差异，采用视电阻率、人工伽马、井径、自然伽马和声波时差等测井曲线对袁店一井煤矿105采区10煤层构造煤进行识别。研究结果表明：105采区煤体结构复杂，构造煤发育，主要分布在采区南部边界、中部以及东部区域构造复杂位置处。

Abstract: In China’s Huaibei mining area, complex geological conditions lead to frequent coal mine gas outburst disasters, which seriously threatens production safety. The results show that coal and gas outbursts mostly occur in the tectonic coal development area. Based on the differences in physical structure and chemical properties between structural coal and primary coal, this paper uses logging curves such as apparent resistivity, artificial gamma, well diameter, natural gamma and sonic time difference to identify the structural coal of 10 coal seams in the 105 mining area of Yuandian No. 1 Coal Mine. The results show that the coal structure in the 105 mining area is complex and the tectonic coal is developed, which is mainly distributed in the southern boundary, central and eastern regions of the mining area.
