摘要
针对某矿大断面巷道贯通交叉点处围岩变形严重、应力集中高、影响安全生产等因素,基于相关研究成果和该矿围岩岩性特点,有针对性地设计出不同区域的支护方案。通过现场顶板离层监测表明,该支护方案具有良好的经济效果,具有积极的技术借鉴意义和应用价值。
In view of the factors such as serious deformation, high stress concentration and influence on safety production of the surrounding rock at the crossing point of a large section roadway in a mine, and based on the relevant research results and the lithology characteristics of the surrounding rock in the mine, the supporting scheme in different areas is designed pertinently. Through the monitoring of the roof separation layer on site, it is shown that the supporting scheme has good economic and technical effects and has positive technical significance and application value.
