浅埋煤层长壁综采工作面矿压显现规律实测分析OA
Field measurement analysis on behavior law of mine pressure on long-wall face in shallow seam
为掌握浅埋煤层大采高工作面开采矿压显现特征，针对鄂尔多斯地区某矿222205工作面矿压观测为项目背景，分析工作面矿压显现规律与煤体内应力分布特征。研究表明：工作面初次来压步距为13.75m，周期来压步距为在8.5m~17.5m之间。该工作面初次来压期间工作面动载现象明显；支架日常工作阻力基本呈正态分布，支架受力状态较为理想。煤体内支承压力分布受采动影响较显著。
Based on mineral pressure observation of 222205 working face in in the Erdos area coal mine, this paper analyzes emphatically about the loading distribution of the powered support and The characteristics of stress distribution in coal to master the characteristics of the ground pressure in the high-cutting and shallow depth coal seam. Research shows that first roof pressure distance was 13.75m and the periodical pressurized distance was 8.5m to 17.5m. Dynami…查看全部>>
