摘　　要：为解决地下矿中深孔布孔设计过程中人工交互主观性大、布孔调整繁琐复杂、孔底距均匀性难以保证等问题,提出一种地下矿中深孔参数化布孔设计方法。总体思路为:结合爆破边界空间约束和爆破参数要求,运用参数化布孔设计思想构建地下矿中深孔参数化布孔设计数学模型,并采用运筹学方法解算数学模型得到最优布孔设计。研究成果在数字采矿软件平台中开发实现,并应用于某地下矿中深孔布孔设计。试验研究表明:人工交互布孔孔底距标准差分别为0.08 m、0.10 m、0.07 m、0.07 m,参数化自动布孔分别为0.02 m、0.03 m、0.02 m、0.02 m,且布孔时间从4 h缩短至5 min。提出的地下矿中深孔参数化布孔设计方法极大地减少了设计技术人员工作量,最大程度保障了炮孔间孔底距均匀性,避免人工设计的随意性和易错性。A parameterized hole placement design method for medium-depth holes was proposed to solve the problems of large subjectivity of manual interaction,cumbersome and complex adjustment of hole placement and difficulty in ensuring the uniformity of hole bottom distance.Firstly,a mathematical model in underground mines was constructed using the parameterized hole layout idea combined with the blasting boundary space constraints and blasting parameter requirements.Furthermore,the mathematical model was solved using the operation research method to get the optimal hole design on a digital mining software platform.Finally,the model was used in an underground mine.The result shows that the standard deviations of the bottom distance for the manually laid holes are 0.08 m,0.10 m,0.07 m and 0.07 m,respectively,while those for the automatically laid holes with the parameterized method are 0.02 m,0.03 m,0.02 m and 0.02 m,respectively.The hole laying time is shortened from 4 hours to 5 min.The proposed method significantly reduces the workload of the designing technicians and maximizes the guarantee of inter-hole laying between holes.It maximizes the uniformity of the bottom distance and avoids the randomness and error-prone nature.
