Intelligent Identification and Automatic Control of Comprehensive Working Conditions of Top Coal Caving
In the study of automated top coal caving in fully mechanized mining,sudden chan-ges of working conditions have an impact on the accuracy of coal gangue identification during top coal caving.Therefore,according to the different γ-ray radiation intensities in coal and gangue,the natural γ-ray method was used to identify the coal gangue mixture,monitor the changes of γ-ray radiation intensity during the top coal caving process,and determine the top coal caving.Fi-nally,an automatic control system was designed based on the natural γ-ray method to guide the movement of the hydraulic support tail beam and realize the automatic top coal caving.
