基于无人机影像的露天煤矿短期生产计划可视化编制

Short term production planning of open-pit coal mine based on UAV data

为提高露天煤矿短期(日、周)生产计划编制效率、快速分析设备计划完成情况以及可视化设计和直观性表达的效果,提出基于无人机影像数据进行短期生产计划快速编制,利用C++语言开发了基于无人机影像的露天煤矿短期生产计划可视化软件系统(Intelligent Mining Design Software System),简称“IMDS”软件。结果表明:①采用无人机影像数据进行短期计划的编制可视化视觉效果增强;②采用无人机影像数据进行局部1500 m×1500 m范围的露天煤矿采场台阶线自动生成,用时为17.392 s,而人工绘图需要5 min;③利用软件平台编制周计划、日计划,降低采矿人员需要反复去现场查验的频率以及突破传统采矿实体、块体算量的复杂性,内部预设设备能力分析模块,直接分析出短期计划内设备完成情况信息;④基于影像数据进行斜坡道快速绘制,自动计算坡道填挖土方量,实现运输道路修筑的精准性;⑤“IMDS”软件提供十大功能模块,235个子功能,可实现对无人机影像数据短期计划编制和基于三维地质实体模块的月度、年度计划快速工程量和工程位置精准确定的编制;⑥短期生产计划编制后,可通过数据发布的方式将短期生产计划发布至露天煤矿综合管控平台,实现计划数据直观展示,实现数据一数一源,保证了数据的准确性和安全性。该系统软件的开发,有助于促进智能化采矿设计软件系统的进一步发展。

In order to improve the efficiency of making short-term(daily and weekly)production plan,fast analysis of the completion of equipment plan and the effect of visual design and visual expression,based on the UAV image data,the paper puts forward the method of making short-term production plan quickly,and develops the Intelligent Mining Design Software System by C++language,“IMDS”software for short.The results show that:①the visual effect of short-term planning is enhanced by using UAV image data;②the Stope Step Line of opencast coal mine in the range of 1500 m×1500 m is automatically generated by using UAV image data;The time is 17.392 s,but the manual drawing takes 5 min;③the weekly plan and daily plan are made by using software platform,which reduces the need of repeated on-site inspection by miners and the complexity of calculation of traditional mining entity and block,the internal pre-equipment capability analysis module directly analyzes the short-term plan of the completion of equipment information;④based on image data for ramp rapid rendering,automatic calculation of ramp fill and excavation volume,to achieve the accuracy of transport road construction;⑤“IMDS”software provides 10 functional modules,235 sub-functions,the short-term planning of UAV image data and the rapid monthly and annual planning of engineering quantities and precise determination of engineering positions based on three-dimensional geological entity modules can be realized;⑥the short-term production plan can be released to the Integrated Management and control platform of opencast coal mine by the way of data release,which can realize the visual display of plan data,realize the data one by one,and ensure the accuracy and safety of data.The development of the system software contributes to the further development of the intelligent mining design software system.
