石门揭煤瓦斯抽采钻孔参数自动优化设计及应用

高瓦斯或突出矿井石门揭煤前，需要设计抽采钻孔并将钻孔位置立体展现在巷道与煤层交互面上。为解决普通AutoCAD等绘图软件无法满足大量计算的问题，本文结合煤矿瓦斯抽采的相关规定，基于Matlab软件编程，采用匈牙利算法和模拟退火算法，开发了石门揭煤瓦斯抽采钻孔参数的自动优化设计软件。应用结果表明:①自动优化设计软件可以解决基于任意煤层、巷道空间位置、抽采输入条件下的钻孔参数自动优化设计和方案对比问题，极大提高了计算效率和准确率；②图像绘制功能可以实现钻孔轨迹立体化呈现；③在确定抽采钻孔参数基础上同步设计验证钻孔布孔参数，实现抽采设计、验证的闭环控制；④实现任意补孔参数设计功能，大大提高了自动优化设计软件的实用性，解决了井下补孔参数设计问题。应用石门揭煤瓦斯抽采钻孔参数自动优化设计可以获得最优化抽采钻孔参数，极大提高了煤矿现场技术人员工作效率，为煤矿智能开采提供了重要支撑。

Automatic optimization design and application of drilling parameters for gas drainage in cross cut coal uncovering

Before uncovering coal in crosscut of high gas or outburst mine, it is necessary to design drainage boreholes and display the position of boreholes on the interaction surface of roadway and coal seam.In order to solve the problem that common AutoCAD and other drawing softwares can not efficiently meet the needs of a large number of calculations, combined with the relevant provisions of coal mine gas drainage and based on Matlab software programming, utilized Hungarian algorithm and simulated annealing algorithm, the automatic optimization design software of drilling parameters of crosscut uncovering coal gas drainage is developed.The results show that: ①the automatic optimization design software can be used to solve the problems of automatic optimization design and scheme comparison of drilling parameters based on any coal seam, roadway spatial position and extraction input conditions, which greatly improves the calculational efficiency and accuracy; ②The image drawing function realized by programming can realize the three-dimensional display of drilling track; ③On the basis of drilling parameters, the parameters of drilling layout are designed and verified synchronously to realize the closed-loop control of design and verification; ④The function of arbitrary hole filling parameters greatly improves the practicability of the automatic optimization design software and solves the problem of hole filling parameter design.The application of automatic optimization design of gas drainage borehole parameters in crosscut uncovering can obtain the optimal drainage borehole parameters, greatly improve the work efficiency of field technicians in coal mine, and provide important support for intelligent mining in coal mines.
