Research and application of coal mining face 3D geological spatial analysis method

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.
