The rights and interests value of mineral resources includes the prospecting rights value and the mining rights value. The mining rights value is made up of the mineral resources value and the compensation value based on the inputs of capitals and labors
Utilized fundamental theory and analysis method of Incomplete Information repeated games, introduced Incomplete Information into repeated games, and established two stages dynamic games model of the local authority and the coal mine owner. The analytic re
This peper proposes the expression of the jigging bed porosity based on the jumping height of the jigging bed and water wave. This kind of expression can help to realize the jigging process automation and intelligence. The computer detection system is als
In this paper, the method of vibration measurement and modal analysis for AM~50 Tunneller machine is presented. When the machine was used for cutting man-made coal bed and real coal bed, the vibration of the machine was measured and the results of signal
The life cycle of technology is one of the most important indexes to weigh up the risk of the investment to neo-tech. There are so many uncertainties because it is conditioned by a lot of factors, we can not make a rational forecasting by traditional asse
Safety Incentive mechanism and corresponding motivation avenues are helpful and important for the scientific safety management in coal mine. With the help of modem systematic analysis method, the effcacy of safety incentive mechanisms is discussed in deta

The oxidation heat of coal is the direct reason leading to coal spontaneous combustion.When coal is exposed in oxygen atmosphere, the physical adsorption and chemisorption happened, and then which resulting chemical reaction followed heat between coal and
The solutions widely used at preeent for calculating complicated mine ventilation networks are ones in which resistance of the branches and characteristic parameters of the fans are taken as basic input data. But it is time-and-energy-consuming to obtain
Based on a comprehensive material and research, various factors are analyzed that influence coal depleted cities\' economic development. From this analysis investment countermeasures are put forward for the coal depleted cities\' economy development.
