A Method of Displacement Detection of Mine Hoisting Container

设计了一种基于编码电缆/旋转编码器多传感器组合测量的位移监测系统,用于测量深井中矿井提升容器的深度。该系统中编码电缆分段铺设在矿井中段附近,相邻的两段编码电缆之间用多芯电缆连接,通过编码电缆实现提升容器爬行停车时的位置高精度检测;测量过程中编码器全程测量,并且与编码电缆的数据进行相互参照。介绍了硬件及软件系统的设计,实验结果表明:该位移监测系统能够保证提升容器在爬行停车时的位移检测误差在6 mm以内,提高了提升容器运行时的可靠性和安全性,为实现超深矿井开采创造了良好的条件。

A kind of displacement monitoring system based on coded cable / encoder is proposed. In this system coded cables lay near the mid-segment of the mine, and two coding cables are connected with multi-core cable. When the mine hoisting container is going to stop, the system can realize high-accuracy detection of displacement of the mine hoisting container. The encoder is used in whole process and the data of the both are referenced to each other. The design of hardware and software systems are introduced. The experimental results show that the displacement monitoring system designed can ensure the displacement detection error of mine hoisting container is less than 6mm while crawling and parking will improve the system reliability and security and create a very good condition for the ultra deep mine mining.
