The Capacity Study On Special Cooling And Dust-removal Unit Of Coal Mine Working Face

With the developing of mine depth, the problem of high temperature and high humidity becomes more and more serious. The deeper the exploring depth is, the higher the temperature is. In a worldwide sight, the main factors leading to mine's high temperature and high humidity harm are below: earth heat, the heat of running machine, the heat of mine material on transport, the self-condensing heat of air when falling. To some particular mine, the springing of hot water, strong oxidant also contribute to the harm.On the other hand, the dusty air is another problem which is in an urgent need to solve. The dust air is mainly formed of micro coal dust and rock dust,which has a direct harm to the body health and working safety. Thus it is no delay to release the problem of high-temperature and air dusty.This paper focuses on the testing of the experiment platform about the cooling and dust-removal ability. To certify the possibility of putting it into the practical mine work. By monitoring the condition of mine working face, including the temperature, humidity, dust concentration and the similar particle diameter distribution, through the changing of conditions, we can get the concrete result about the air-conditioning and dust-removal capacity, then finding out the way to imprve the situation,.The equipment can reach the efforts of cooling and dust-removal at the same time, thus it can get used to the condition of mine which has a special high temperature and humidity. The experiment platform is built, and after the testing, we find out the problem and the points should be developed, then improve its capacity in order to make it fit the mine work perfectly.
