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 mine water inrush is a very difficult problems which should be solved more earlier, and it have long plagued safe production of coal mines. The reliable operation of coal mine drainage systems plays a vital role in safe production of coal mines. Based on the non linear relationship of the state parameters of the coal mine drainage facilities, we propose a safety monitoring method based on BP...
This article describes the design of a wireless sensor network based on ZigBee technology. It is mainly used for collecting and transferring the various monitoring information about the coal mine underground. Then the data will be analysed and processed in the monitoring system outside, so that we can ensure the safety of the coal production and effectiveness better.
In order to monitor the production condition exactly and real-timely in underground and surface of coal mine, a new mobile application solutions scheme based on TD-SCDMA in coal mine is proposed. According to the high speed data service of third generation mobile communication systems, the wireless network of surface scheme was designed by the C/S structure, which can provide mobile communication...
It is necessary to guarantee that timely diagnosis of fans of coal fault is for mine safety production in enterprises. To establish fans of coal fault diagnosis expert system is a kind of effective way for improving fans fault diagnosis. The roughness set is applied to fans fault expert system for knowledge; this way can improve the objectivity of mining knowledge, which to establish effectively fans...
The temperature field is one of the most important parameters of combustion safety in boiler. In this paper, acoustic pyrometry, a new diagnosis tool of combustion safety in boiler, is given. The principle of acoustic pyrometry is introduced. The unique benefits of diagnosis on combustion safety are described. Two key techniques of acoustic pyrometry, the measurement of time of flight (TOF) of sound...
