Abstract
It is dififcult to manage the broken roof of the fully mechanized coal mining face in soft coal seam, and the roof leakage phenomenon is easy to occur during the extraction process. Taking the 21090 working face as an example, through the water injection in coal seam, roof lapping and chemical grouting and other means effectively improved the integrity and strength of the roof, reduce the roof leak rate and take leakage degree, laid the foundation to ensure the safe mining of the working face.关键词
