用智能化仪器监测综采工作面支护质量

Monitoring the Supporting Quality of Fully Mechanized Working Face With Intelligent Instruments

介绍了钱家营矿使用智能化井下监测数据采集仪和计算机数据处理程序在综采面顶板状态和支护质量监测中的应用情况。这一先进技术的应用大大提高了综采面工程质量、改善了顶板状况,减少了顶板事故。

A routine, all-sided monitoring upon the undergroupdpressure for knowing the supporting qualiyty on a fullymechanized face is a significant way of well controlling theroof and enhencing the output of the face. The intelligentinstruments of underground pressure data collector and com-putor data processor used at Qianjiaying Mine of KailuanCoal Mining Administration providers an advanced means forunderground pressure monitoring. It can not only monitorthe underground pressure, but reflect the operation level ofminers and discover the problems of supporting quality intime. The practical tests at fully mechanized face 1171 ofthat mine showed a efficiency 3-4 times that of the mechani-cal instruments and 120 times that of manual processing.Futhermore, the monitored results can be fed back to theworksite, resulting in a reduction of the roof fall by 9423%. support failure by 1.59% and in a raise of themonthly output by 56.8%
