Study on the High Carbon Dioxide in Repeated Mining Coal Seam of Tangshan

Abstract:

With the development of economic and the shortage of energy, repeated mining is an important measure. Based on the production characteristic of small coal in Tangshan, the situation and existing problems of small coal mining was Summarized; with years of practice in mine ventilation technology and teaching experience, a part of the mine gas level identification results were analyzed and discussed; the result is that the repeated mining of Tangshan was a low gas mine, but the carbon dioxide emission was too high; The results show that the reasons of high carbon dioxide emission, which were abandon coal spontaneous combustion and wooden support decayed and geological and mining technology. The measures of control high carbon dioxide are proposed. The study result is important to improve safety production in the repeated mining coal.
