Building and application of highly-precised apparent geologic model for thin coal seam
During the construction process of the intelligent working face of Shaanxi Shuanglong Coal Mine,the operational efficiency of intelligent mining equipment is severely restricted due to the limited operational space of mining of thin coal seam.Based on the comprehensive analysis of geologic conditions,we carried out the building of highly-precised apparent geologic model to boost the precise degree of intelligent mechanized mining.The strata model and fault model were estab-lished based on the comprehensive geologic exploration data,and combined the practical situation of roadway,the geologic model was dynamically updated for improving the precision,keeping the precision of the geologic model roof and floor is within about 0.2 m within the range of 50 m in front of mining.Our study provides reference for the intelligently precise mining of thin coal seam,thus reducing the working intensity of miners and improving working efficiency.
