大直径深孔爆破参数智能识别辅助设计

Intelligent Identification and Auxiliary Design for Blasting Parameters of Large Diameter Deep Hole

针对大直径深孔爆破在实际生产操作过程中工作量大、操作繁琐、结果易错等特点,通过对该种爆破工艺流程和分段装药、分层间隔装药结构的分析,采用Visual Lisp二次开发了一款辅助设计软件。该辅助设计软件基于Visual Lisp对Auto CAD进行二次开发,形成交互式用户界面操作模式,通过用户选取图形中的图元,智能识别大直径深孔爆破分段装药、分层间隔的孔内药包数量、装填界限、雷管段数等关键结构参数,结合Microsoft Active Automation的接口进行数据读写,自动实现图纸上的图形几何参数的提取与Excel电子表格的交互操作。该软件成功应用于凡口铅锌矿采场生产爆破,实现了图到表转换工作的高效性和可靠性,减轻了技术人员的劳动强度,提高了整个爆破设计施工过程的工作效率。

For heavy workload, tedious and error-prone characteristics in the actual operation process of large di- ameter longhole blasting, an assisted design software was developed by Visual Lisp. The structure of the staged charge and the stratified charge, the interactive user interface operation mode were formed by this assisted design based on the secondary development of Auto CAD by Visual Lisp. The user can select the graphic elements in the graph to in- telligently identify the key information including the filling boundaries and the number of packs and detonators of the large-diameter deep-hole blasting segmented charge. Combining with Microsoft Active Automation interface for data reading and writing, an interactive operation between the drawings on the extraction of geometric parameters and Ex- cel spreadsheet was automatically achieved. This method was successfully applied to the Fankou lead-zinc mine stope blasting production, which achieved a conversion among map, table efficiently and reliably. The method reduces the labor intensity of the technical staff and improves the efficiency of blasting design and construction.
