[Abstract]:In order to improve the rescue equipment of non-coal mines in China and to improve the level of mine safety protection and emergency rescue ability, the paper determines the function orientation and technical index of the underground refuge chamber in Jinxiuzhuang Gold Mine, Shandong Province, in view of the basic situation of the gold mine. The composition of indoor environmental control system is studied, and the emergency exhaust system and emergency drainage system for flood protection shelter are put forward. It provides an important basis for the design of shelter chamber in non-coal mines and the formulation of relevant standards and regulations. By single factor and orthogonal experiment, the effects of particle size, length of CO2, moisture and additives on the adsorption properties of sodium lime were studied. The optimum formulation and molding process of the new CO2 adsorbent were determined. A multi-drive air purifying device for shelter chamber is designed and developed. The device uses mine air pressure, storage battery and manpower as power source, including pneumatic mode, electric mode and hand mode. The flow patterns of the purifier under three operation modes are analyzed by Fluent numerical simulation, and the experimental results are verified to be true and reliable. Based on the unreacted kernel model, the kinetic model of sodium lime adsorption CO2 reaction was established, and the influencing factors of reaction rate were analyzed theoretically. In this paper, the technical parameters and internal structure of the ice storage refrigeration system are studied, and the formula for calculating the minimum circulating wind speed of the ice storage air conditioning system is put forward, and the refrigeration performance of the storage refrigerator is tested through experiments. The influence of different amount of residual ice on refrigeration power is analyzed. The effects of inlet pressure, ambient temperature and the opening of hot valve on the basic performance of vortex tube are studied experimentally. The application and combination of vortex tube in the chamber are determined, and the noise reduction design is carried out. Based on the experimental study of the chemical reaction characteristics of potassium superoxide, a kinetic model of the reaction of potassium superoxide is established, and its chemical reaction mechanism is expounded. In view of the easy sintering, melting and low utilization rate of potassium superoxide tablets, The problems of slow initial reaction rate and difficulty in matching human respiratory entropy were studied and a new type of air regeneration device was proposed. The reliability and stability of the indoor system and environmental control equipment are verified by 48 hours manned test of 50 people in the underground refuge chamber. The environmental parameters of the chamber and the movement state of the personnel are analyzed, and the human body is in different active states. The survival parameters such as CO _ 2 production and respiratory entropy of oxygen consumption in different periods and different oxygen concentrations have been determined, and the minimum pressure and air volume to meet the survival needs of safe havens has been determined, which provides an experimental basis for the establishment of relevant standards and specifications for emergency risk avoidance and so on.
