An attempt has been made to study the mechanism of utilizing geothermal energy to preheat the air flow in shallow drift and its practical applications. Hence a new calculating method based on definite difference theory with the aid of computer is developed.Summary. Mathematical models involving the radial distribution of rock temperature) the axial distribution of air flow temperature and the relevant preheating parameters in the heat-exchange process between country rock surrounding a drift and air flow in drift are set up and shown by a flow chart (cf. Fig.10). Some new viewpoints are put forward to describe the air-geothermal preheating mechanism and its application as follows.1. The periodic variation of superficial atmospheric temperature leads the distribution of rock temperature surrounding drift to fluctuate periodically. As a result, the country rock surrounding a shallow drift serves a function as heat reservoir to regulate intake air temperature under heat-exchange. The heat resource which is used to preheat intake air in winter derives itself mainly from the heat absorbed and stored by country rock from warm air flow in summer.2. In summer, the renewal of heat retained in rock with fan-ventilation is much better than that without fan-vetilation. To ensure the preheating effect in winter from heat loss, the drift zone to be preheated should be fan-ventilated at the time when the superficial atmospheric temperature raises to an annual peak and then closed thereon. In winter, the starting time to preheat drift zones should be retarded as far as possible so as to provide the heat requirement for severe winter.3. A thermal hysteresis phenomenon occurs in the interval from the time of hardest preheating to the time when intake air having lowest temperature.In conclusion, preheating technique utilizing geothermal energy in waste drift or in goaf (sometimes, if necessary, a few of exclusive drifts are excavated) is superior to that by other ways in both cost and technology.The method presented in this paper can be used to solve the problem of air-cooling in deep mines as well.
