As a modern security design, Inherent Safety means that equipment and facilities is able to contain the inherent fundamental features to prevent accidents. Mine hoist is the most important equipment in the coal production. How to achieve safe, reliable, efficient production, has been the focus study at home and abroad. Inherent safety is reflected in hoist design, primarily through the design measures...
Because of the limit of the domestic configuration software which is in the use of scrutinizing the coal mine, the ActiveX technique is discussed and the design of the safety of coal mine, which utilize the ActiveX technique, is actualized. The fig of system frame and the implementation of part of modules are also given. This system can provide the friendly interface for the controlling of coal mine,...
It is very important for ensuring the mine's safety and protecting the environment to inspect the concentration of CH4 in time. It is advantageous for control center to keep fluent communication with far excavate coal spot; it enhances the safety factor and solves the problem of telecommunication. The cost of system is low and the quondam communications cable can be used.
Based on systematic collection of the hydrogeological data of coal mine, we analyzed the factors affecting water inrush from coal floor and determined the major factors. We used the fuzzy clustering method to evaluate the water inrush risk from coal floor in order to solve the evaluating limitation of water inrush risk from coal floor by the water inrush coefficient method. The fuzzy clustering method...
The upgrading of China's coal mine detection equipment and technical means are very backward, mainly distributed instruments and devices, low efficiency, poor accuracy, detection and testing of the limitations of the data, testing methods, data-processing technology is backward. Unable to provide an objective and impartial technical data to meet modern coal mine production safety needs. In this paper,...
