| 摘 要： | 利用相似模拟实验技术,分析了澄合矿区5号煤层4 m采高综采开采覆岩活动规律、工作面矿压基本规律和特征以及对工作面支架载荷的影响,实验得到:采场支架载荷较普通综采面高,老顶来压明显,但不剧烈,冲击载荷小;周期来压期间支架载荷及动载系数大于初次来压期间支架载荷及动载系数,这为确定合理支架工作阻力和提高顶板控制效果提供科学依据。

| Abstract: | Based on similar simulation test,research the movement rule of overlying strata,regularity of mine pressure and support resistance on thick seam in fully-mechanized coal mining face in chenghe mining area,through the similar simulation test,analysed the following conclusions: the load of support in the workface is bigger than the general mechanized faces;the coefficient of dynamic load is littler and there is no impact load when weighting,the support load and coefficient of dynamic load are bigger during th... |
