Abstract
In the process of mining fully mechanized top coal caving face, if meet the geological structure belt or advancing speed is too slow , will cause the broken roof, the increase of tip-to-face distance, spalling, roof leakage, even to caving to hollow upon the safety bracket, which buried the huge hidden trouble. Sanhekou coal mine using Ma Li pre-grouting to keep the integrity the roof made a success, and achieved good economic and social benefits.关键词
