Development Of The Mining Intelligent Thermometric Indicator For The Hole In Mine Fire Resistance

The coal spontaneous combustion is one of the most greatly calamity in our country. According to the incomplete statistics, 60 percent of state-mines have the dangerous of spontaneous combustion. Generally, it is difficult to work against the fire hazard when it's take place under the mine. It is a comparatively effective scientific and technological means to measure hole temperature and make the scheme against fire with the drilling towards to the fire field. With the collection of the temperature information parameter, it can apply the reliable reference for the sureness of the scheme against fire. So this thermometric indicator instrument has been developed for the collection of the hole temperature information.The development process of this intelligent instrument has been described in detail in this thesis. On the basis of drawing lessons from the experience in the past ,the new instrument has been developed with combine improving some electronic such as the new generation micro controller, power , sensor, electric circuit, digital chip and etc. Through the debugging and application during the laboratory and on the spot, it offers the reliable means for the prediction of the fire district as well as saving a large amount of fund and working efficiency. At the same time, it can prove that the item has an important popularization and application prospect.
