基于三维地测模型具有直观、全面等优点,利用三维地测模型可使回采工作面地质信息查询与分析工作更加简捷、方便,提出了基于地测模型的煤矿回采工作面三维地质空间分析方法。建立了三维对象属性的参数化处理、交互式三维工作面空间位置标定、危险源缓冲区分析、地表地下叠置分析等计算模型。在矿山三维虚拟环境系统之上,对相关计算模型进行了设计实现,构建了工作面空间分析报告自动生成软件,并在示范矿井中进行了实际应用。结果表明:三维地测模型使用户能够更加直观的了解地面、井下巷道和重大危险源的空间关系;自动化工作面空间分析方法使技术人员分析危险源的时间缩短了30%~50%,提高了煤矿地测日常工作效率。

The 3D geologi al survey model has the advantages of ititiveness and vistilityso using the mcdel can reduce working hours of the geological informafion quary and anaysis Based on 3 geogicalsurvey mode ,wrorking face spoatial analysis methods were put forward.Firstly the computational models of paraneterized processing of 3D objet properies lbeling the working face lcation bufifer analysis of hazards o veray analysis ofground and underground were established.Then,atter bulding the 3D orual mine enironment.the computatonal models were implemented Finally.the report auomatic generation sofiware of the wrking face spatal analysis was developed,and the practical appication ofthe software in coal mines was aso caried outThe resuts show that the 3D geological survey nodel makes it more intitve to understand the spatial relatons among the ground,underground roadways and major hazard sources.The time of anaiyzing hazard sources by techical personel can be shortened by 30%×50% and using the automatic spatal analysis method of working faces,the dally wors efricency in coal mines can be improved.
