Water Regime On-line Monitoring System For Undersea Mining In Beizao

Beizao coal of Mining Group Limited Company is the first coal mining undersea mine in China.The key of mining under sea is crucial to prevent the water in theprocess of exploitation to burst into the underground mines, therefore there hasparticularly important sense in the process of mining and roof aquifer water regimemonitoring and warning.They has done a large number of mining under surface water and mining undersea water prevention and control technology of survey and research work beforemining under sea, Based on the early and research institutes in the process of miningthe ocean sea water bursting mechanism analysis and disaster early warning systemand emergency response plan, with the help of the Ethernet ring network, with the aidof mine safety monitoring system and KJ95strong transmission, storage and terminaldisplay function, the hydrological monitoring system in every observation point isbeen as a sub-station in the article, and through the system in the office computer andproduction scheduling big-screen display in real time the observation hole water andeffluent water quality data and abnormal warning, realizing the mine water real-timeon-line monitoring; at the same time the realization of original observation data, theyear changes curve query; analysis and summary of main aquifer in mine coal stratumof groundwater level and water quality change trend of water level change, forecast,looking for the aquifer water quality characteristic ions, through the water level andwater quality changes in amplitude size, identify the warning threshold, once theoccurrence of abnormal timely warning, the system makes full use of to Inoue WaterHydrological monitoring, for safety mining under waters provide protection. Therehave been five working surfaces sea area in mining under sea, and produced about fourmillion tons of coal, also will be henceforth mining, especially in shallow miningwater prevention and control to provide security protection.
