Abstract: The roof of the 3308 fully mechanized top coal caving face in Wangpo Coal Mine is hard and massive as a whole. After coal seam extraction, the initial weighting interval is long and the dynamic loading factor is high, with the initial caving interval reaching 30 to 50 m and locally exceeding 50 m, posing safety risks due to large roof overhang area and the potential for large-area collapse. To address these issues, deep-hole presplitting shaped charge blasting was carried out in the 3308 return airway to pretreat the stope roof and promote its timely collapse. Field observation of the roof strata using a borehole camera shows that the strata are well intact. Based on a comparative analysis of the breaking depth and blasting engineering quantity, end presplitting blasting was determined as the roof control method, and the site construction design was completed accordingly. Analysis of monitored mine pressure data indicates that the initial weighting interval ranges from 27.8 m to 37.2 m, averaging 34.3 m. Compared with the calculated results based on beam theory and plate structure theory under untreated roof conditions, the large-area roof hanging in the stope has been significantly improved after the application of end presplitting blasting for roof control.
