| 摘 要： | 通过对43上03工作面超前支承压力现场实测,分析了煤壁前方沿走向和倾向压力分布规律,研究认为43上03工作面回采期间巷帮实体煤侧煤层沿走向在工作面前方存在支承压力峰值,而巷帮实体煤侧煤层沿倾向在工作面前方应力峰值并不明显,临近工作面时煤层应力均处于应力降低区。

| Abstract: | Through the actual measurement for advancing support pressure at the 43 up 03 working face, the tendency pressure distribution rule is analyzed in front of the coal wall along the trend. The research thought that the 43 up 03 working face return pick the period lane to help the entity coal side coal bed to have the force of support peak value along the trend in front of the working face, but the lane helps the entity coal side coal bed the stress peak value not to be certainly obvious along the tendency in front of the working face. Approach-ing the working face the coal bed stress is in the stress reduceing area. |
