摘要:

为解决韩城矿业桑树坪煤矿顶板破碎、片帮严重导致的支护作业效率低下、工艺复杂的问题,通过分析TBM快速掘进系统整体空间布局,提出了基于空间重叠系数的钻锚设备布局评价方法。文章构建基于支护需求、钻锚设备布局、作业范围约束的TBM钻锚系统空间布局优化模型,求解出钻锚系统最佳布局方案,结合钻锚支护工艺需求,研究了基于动态变步长的RRT-Star轨迹规划方法,实现了基于任务驱动的钻锚设备快速轨迹规划。针对多目标多工序的钻锚工艺优化问题,以时间最短为目标,构建了钻锚工艺优化模型,求解出最优钻锚工艺排布矩阵,并基于最优工艺排布矩阵,模拟出钻锚系统实际工作过程。经过实际工程应用效果验证,优化后的TBM钻锚系统空间布局、轨迹规划方法及钻锚工艺,能够显著提高TBM 快速掘进系统的作业效率。
