煤炭是我国主体能源，随着我国煤炭开采向深部发展，煤层高地应力、高瓦斯压力、低渗透性特征愈发显著，易造成瓦斯超限及煤与瓦斯突出事故。为降低瓦斯灾害，煤层钻孔预抽是防治瓦斯灾害的主要方法之一，其中钻孔布置与三维应力条件下煤体解吸渗流及变形特性有关。通过研究真三轴条件下不同有效应力对煤体瓦斯解吸渗流与变形影响规律，为煤层瓦斯高效预抽提供一定依据。

论文研发了煤体瓦斯吸附解吸与渗流全过程真三轴实验平台，实验平台主要由高压腔体、应力加载及控制系统、注气-吸附-解吸系统和数据采集及控制系统等组成。选择典型高瓦斯矿井煤样，探究了真三轴条件下有效应力对煤体瓦斯吸附解吸渗流及煤体变形特性的影响，得到了吸附量、解吸量、渗透率、形变量等不同实验参数，发现煤体瓦斯累计解吸量随解吸时间呈Langmuir型增长，煤体渗透率与有效应力呈负指数关系。

通过煤体瓦斯扩散渗流方程、变形控制方程、煤体破坏准则方程等，结合固体力学、流体动力学、渗流力学等基础理论，建立真三轴条件下煤体瓦斯解吸渗流及变形多物理场耦合模型。通过COMSOL Multiphysics数值模拟软件，研究不同有效应力作用下煤体瓦斯解吸渗流与变形特征，模拟结果与实验结果具有良好一致性，煤体瓦斯解吸量的绝对误差为0.0286，煤体渗透率的最大绝对误差为3.04，验证了数值模拟模型的可靠性。

通过数值模拟，分析了真三轴条件下不同有效应力对煤体瓦斯解吸渗流及变形特征的影响规律，揭示了煤体瓦斯解吸量、渗透率及三轴方向应变量与时间的变化关系，煤体瓦斯解吸量及变形量均与解吸时间之间呈类Langmuir型变化规律。随着有效应力从5.2 MPa增大至9.2 MPa，累计瓦斯解吸量下降43.75%；解吸体积应变下降幅度为87.22%；煤体渗透率下降幅度为82.59%；渗流体积应变下降幅度为87.53%。

以陕煤铜川矿业有限公司玉华煤矿1417工作面为工程背景，应用COMSOL数值模拟软件，优化煤层瓦斯预抽钻孔参数，分析了钻孔直径、布孔间距、抽采负压在不同有效应力条件下煤层瓦斯钻孔预抽效果。有效应力13.42 MPa下，钻孔直径的增大会使得有效抽采半径不断增大；布孔间距的增大使得有效抽采半径降低；抽采负压对钻孔有效抽采半径影响不显著。随着抽采时间的增加，钻孔有效抽采半径呈现增大的趋势，于抽采60 d后趋于平缓。确定瓦斯抽采直径为133 mm，布孔间距为6 m，抽采负压为22.55 kPa。通过现场工程实践，分析了现场不同钻孔抽采时间下瓦斯浓度、混合流量及抽采纯量的变化规律，验证了钻孔方案的合理性，保证了工作面的安全生产。

With the deep development of coal mining in China, the characteristics of high ground stress, high gas pressure and low permeability of coal were becoming more and more significant. It was easy to cause coal and gas outburst. Coal seam drilling pre-drainage was one of the main methods to prevent gas disasters. The borehole layout was related to the desorption seepage and coal deformation characteristics under three-dimensional stress conditions. Studying the influence of different effective stresses on gas desorption seepage and deformation under true triaxial conditions can provide a basis for efficient pre-drainage of coal seam gas.

A true triaxial experimental platform for the whole process of coal gas adsorption, desorption and seepage was developed. It was mainly composed of high pressure chamber, stress loading-control system, gas injection-adsorption-desorption system and data acquisition control system. The influence of effective stress on gas adsorption-desorption seepage and coal deformation characteristics under true triaxial conditions was investigated by selecting typical high gas mine coal samples. Different experimental parameters such as adsorption capacity, desorption capacity, permeability and deformation were obtained. It was found that the cumulative desorption amount of gas increased exponentially with time. It was a negative exponential relationship between permeability and effective stress.

Through the coal gas diffusion seepage equation, deformation control equation, coal failure criterion equation, etc. Combined with solid mechanics, fluid dynamics, seepage mechanics and other basic theories. A multi-physical field coupling model of coal gas desorption seepage and deformation under true triaxial conditions was established. The gas desorption seepage and deformation characteristics under different effective stresses were studied by COMSOL Multiphysics numerical simulation software. The simulation results were in good agreement with the experimental results. The absolute error of coal gas desorption was 0.0286. The maximum absolute error of coal permeability was 3.04. The reliability of the numerical simulation model was verified.

Through numerical simulation, the variation law between different effective stresses and gas desorption-seepage-deformation characteristics under true triaxial conditions was analyzed. The relationship between gas desorption amount, permeability, triaxial strain and time was revealed. There was a quasi-Langmuir type variation law between gas desorption-deformation and time. As the effective stress increased from 5.2 MPa to 9.2 MPa, the cumulative gas desorption decreased by 43.75%. The desorption volume strain decreased by 87.22%. The permeability decreased by 82.59%. The decrease of seepage volume strain was 87.53%.

Taking the 1417 working face of Yuhua Coal Mine of Shaanxi Tongchuan Mining Co., Ltd. as the engineering background. Using COMSOL numerical simulation software. Optimize the drilling parameters of coal seam gas pre-drainage. The effects of borehole diameter, borehole spacing and negative pressure on the pre-drainage under different effective stress conditions were analyzed. Under the effective stress of 13.42 MPa, the increase of borehole diameter would increase the effective extraction radius. The increase of hole spacing reduced the effective extraction radius. The extraction negative pressure had no significant effect on the effective extraction radius. With the increase of extraction time, the effective extraction radius shown an increasing trend. It tended to be gentle after 60 d of extraction. The gas extraction diameter was determined to be 133 mm. The hole spacing was 6 m. The negative pressure of extraction was 22.55 kPa. Through field engineering practice, the variation law of gas concentration, mixed flow and extraction purity under different borehole extraction time was analyzed. The rationality of the drilling scheme was verified, and ensure the safe production of the working face.
