摘要
Abstract
There are a certain technical limitations for the technology of gob-side entry retaining under brittle surrounding rock conditions. Taking Xinzhuang Mine as the engineering background, we studied the stability control of brittle retaining entry and designed the process of roadside filling system and the parameters of roadside filling body, and then we gave a depth analysis on surface & deep surrounding-rock along gob-side entry by a scientific mine pressure observation program. The result shows that:under the brittle surrounding rock and seriously coal wall caving conditions, the technical support system for reinforcement of brittle rock has a good effect on controlling the deformation of the surrounding rock. Moreover, the new high-water material has the characteristics of rapid setting and strong anti-deformation ability that can adapt well to the gob-side entry retaining under brittle surrounding rock.关键词
