摘要
Abstract
According to the ground behaviors of the No 3505 mechanized mining face of Yangying Mine, a full site measurement research was conducted with extraction, analysis and processing of the data from site research. The rock pressure behavior law, abutment pressure distribution and load distribution characteristics of support in the mechanized caving mining face with igneous rock erosion under the condition of unstable coal seam. It’s identiifed that the ifrst weighting step distance is about 33m, the periodic weighting step distance is about 5m, and the reasonable advance support distance is 52.5m.关键词
