摘要：

为解决人工设计高位瓦斯抽采钻孔布置参数误差大、抽采效率低的问题,以新疆某高瓦斯矿井为研究对象,提出一种基于二维物理相似模拟与智能系统的卸压瓦斯高位抽采孔设计思路。通过二维物理相似模拟试验,揭示覆岩横纵向裂隙联动演化特征,精准划分瓦斯运移区(最大高度36.7 m、最大宽度22.7 m)与储集区(最大高度26 m、最大宽度17 m)的几何边界,明确瓦斯赋存空间演化特征。基于Python语言开发高位瓦斯抽采钻孔智能系统,融合OpenGL技术构建3D地质模型,结合钻孔终点与开孔点平距、方位角及终孔高度等参数,通过自主研发的参数计算系统自动生成钻孔布置参数(方位角、倾角、长度),并利用可视化演示系统模拟钻孔轨迹。结果表明:该系统设计的钻孔终孔位置精准位于垮落带上部、断裂带中下部,2号钻场瓦斯抽采体积分数达6.52%~10.94%,较传统方法提高2.52%~5.19%。

Abstract:

To solve the problems of large error of layout parameters and low extraction efficiency of artificially designed high-level gas extraction boreholes, a high-gas mine in Xinjiang was taken as the research object. A design method for pressure-relief gas high-level extraction boreholes based on two-dimensional physical similarity simulation and an intelligent system was proposed. Through the two-dimensional physical similarity simulation test, the evolution characteristics of the horizontal and vertical fractures of the overlying rock were revealed. Additionally, the geometric boundary between the gas migration area (maximum height 36.7 m, maximum width 22.7 m) and the reservoir area (maximum height 26 m, maximum width 17 m) was accurately divided, and the spatial evolution characteristics of gas occurrence were clarified. Based on Python language, the intelligent system of high-level gas extraction borehole was developed, and the 3D geological model is constructed by integrating OpenGL technology. Combined with the parameters such as the horizontal distance between the borehole end point and the opening point, the azimuth angle and the final hole height, the borehole layout parameters (azimuth angle, inclination angle and length) were automatically generated by the self-developed parameter calculation system. Subsequently, the borehole trajectory was simulated by the visual demonstration system. It is shown by the application that the final hole position of the borehole designed by this system is accurately located in the upper part of the caving zone and the middle and lower part of the fracture zone. The gas extraction concentration of 2 # drilling field is recorded at 6.52%—10.94%, which is found to be 2.52%-5.19% higher than that achieved by the traditional method
