为了掌握浅埋深厚煤层综放工作面开采矿压显现特征,通过采用多种监测手段对实验综放工作面的顶板来压规律进行研究。结果表明,随着工作面推进,巷帮不同深度的煤体在超前支承应力和侧向应力的作用下其整体应力变化具有明显的规律性,结合工作面支架的适应性分析,为类似工作面矿压研究提供借鉴。
In order to grasp the appearance characteristic of open pit pressure in fully mechanized top coal caving mining face with shallow depth and high coal seam, the pressure law of roof pressure in fully mechanized top coal caving mining face was studied by adopting various monitoring methods. The results show that with the advancement of working face, the coal body with different depths has obvious regularity in the overall stress change under the advance bearing stress and the lateral stress. Combined with the adaptability analysis of the face support, Ground pressure study to provide reference.
