In order to realize coal mining in safety without moving villages, increase coal recovery ratio, solve the conflict of mining and panel relays, the scheme of paste backfill mining under villages in Xiaotun coal mine is executed, and the surface subsidence observation lines on the surface of the mine are established and timely monitored. Based on the results of the surface movement observation, the...
Coal transportation from Xinjiang to the hinterland china is a strategic program to ensure energy safety. As the most important mode of coal transportation, the railways should adapt itself to the gale weather especially in Xinjiang. New approaches to the optimization of yard longitudinal section design are based on evaluating the performance in respect of construction and operation. In gale weather...
The coalmine gas hazard affected safety of China coalmine production most. As there were lots of complicated and uncertain factors during gas accidents emergency rescue and making decisions process, accurate decisions can not be drawn by mathematics models with present information monitored by the KJ series monitoring systems such as KJ90, so experiences of former questions were urgently required...
Based on the ideology of "using the monitor data to reflect the production safety and using the risk analysis and safety evaluation methods to guide safety management to realize the objection of mine coal safety state warning and assistant decision-making support system", with Bofang coal mine of Shanxi Orchids Corporation's practical experience in safety state management, we set up a warning...
This system utilize sensor, automatic detection, communication and microcomputer technologies, to realize the operational parameter intelligent monitored management of entire mining area. The data acquisition terminal take the 89C52 chip integrated circuit as a core, cooperating highly effective digital sensor, carries on the communication through the RS485 interface with the main control machine,...
