| 摘 要： | 在煤矿开采过程中受地质构造影响工作面会呈现不等长。为了掌握不等长工作面顶板运动规律,在综采支架上安装连续记录智能化压力仪表记录顶板的压力变化。通过理论分析和矿压观测分析可知,随着不等长工作面长度不断加大工作面平均压力随着增大、而周期来压步距有减小的趋势。

Study on Mine Pressure Laws of Unequal Length Working Face |
| |
| Abstract: | In the coal mining process,working face will present unequal length affected by geological structure.In order to grasp the roof movement laws of unequal working face,continuous recording intelligent pressure instruments are installed in fully mechanized mining support to record roof pressure.The theory analysis and mine pressure observation show that average pressure of working face increases with the length increase of unequal length working face,and periodic weighting distance has the tendency of reduction. |

| Keywords: | unequal length working face mine pressure observation periodic weighting |
