Comprehensive Monitoring Programs To Pressure Chen Gui Liu Farm Iron Ore

Ground pressure monitoring for mine safety is becoming more and more importantwith the ground pressure disaster occurred more and more frequently in domestic time. TheStudy of monitoring mine pressure aimed to provide safe, reasonable and efficientguarantee for mining enterprises.This paper takes Chengui Liujiafan iron mine as the research object and establishes acomplete set of the monitoring of ground pressure solutions through comparing thedifferent monitor methods based on the real situation. The following are the main featuresof my work:(1)This paper researches domestic and foreign method of determining ground pressureand chooses reasonable monitoring methods based on the actual situation of ChenGuiLiujiafan iron mine. This paper also establishes a comprehensive monitoring system whichconsists of acoustic emission, rock mass stress, displacement monitoring and real-timeonline monitoring. The reasonable monitoring instruments and monitoring technologyaccording to the scheme of the mining ground pressure has characteristics of pertinenceand can be long-term used. It provides valuable experience for the development of themining ground pressure monitoring technology, and also provides reliable basis for groundpressure control and security management.(2) We can control mine ground pressure disaster by analyzing the monitoring data.The analyze results show: rock acoustic emission average numbers are still remaining rockfailure limit value; The present pillar stress monitoring data indicate that there is nomagnificent underground pressure in various measuring points; The surface subsidence androof displacement changes are in the critical deformation range, so the mine still safe inshort term.
