摘　　要：我国含煤盆地形成后经历了多期次构造运动的叠加改造,矿井构造组合、瓦斯含量分布、煤体结构展布、顶底板岩层富水性分布等呈现出复杂化、非均质化、差异化等显著特征。从瓦斯抽采工程地质新角度出发,结合井下瓦斯抽采实施扰动工艺的迫切需要,开展了基于扰动工艺的瓦斯抽采地质单元区划研究,提出了科学划分出三级瓦斯抽采地质单元原则,初步形成了一套方便工程实践瓦斯抽采地质单元评价指标体系,为扰动工艺和瓦斯抽采工程的实施提供了可靠的地质依据。The coal-bearing strata were a ll subjected to multistage tectonic movement superimpositions andtransformations, so the mine structure, coal body structure, roo f-floo r lithology, hydrogeological condition respectivelypresented a feature of complexity, heterogeneity, diversity and differentiation. From a new perspectiveof the gas extraction, combining w ith the urgent needs of hydraulic fracturing implemented on gas extraction,gas extraction geological unit division based on hydraulic fracturing was studied, it was put forward thatthe principle of the scientific division of the geological unit of gas drainage in three stages, the evaluation in dexsystem of gas drainage geological unit was formed by a set of convenient engineering practice, to providea reliable geological basis for the disturbance process and the implementation of gas drainage engineering.
