The normal operation of electrical and mechanical equipment in coal mine to guarantee the safety in production of coal mine, but the operating process of electromechanical equipment is easy to be affected by the factors of technology, to produce a series of technical failure, can’t guarantee the efficiency of coal production, which become the main factor of coal mine production. Effects caused by the technology of fault of mine electromechanical equipment is relatively large, therefore, through the study of equipment technical fault, proposed treatment measures of science.

The measure method of evaluating coal seam burst is systematically introduced. In order to find the danger of coal seam burst, and improve the methods of forecast and prevention, several testing methods for rock burst are used to evaluate the danger of coal seam burst. Through the measurement in the underground and experiment in the lab, the danger indices of coal seam burst are synthetically analyzed, and the method of forecasting the danger of coal seam burst is provided for the mines.

The goal of coal railage is to seek for employee, coal and other cargo transportation with high efficiency, in reason, economy and safety. One of the main task in coal railage is to improve van's operating efficiency. So the important aspect of transportation organization work is to analysis cargo stay time and try to shorten it. In this paper, starting with analyzing factors which affect cargo stay time, are some measures to shorten cargo stay time.
