确定煤堆和透过它的空气之间热和质量交换的参数,对于制订新的和完善现有的预防内因火灾的方法,有很重要的意义。 为了研究该问题,对东方煤炭工业安全生产科学研究所的工作人员所作的实验结果进行了热力学分析,实验室设在普罗科皮耶夫斯克煤炭联合公司加里宁煤矿管理处的厚12～13米、倾角64～66°的煤层中。在三个断面为8×9米~2、长45米的每个峒室中储煤2700吨,并使其保持在适合煤自燃条件的最佳漏风空气动力状态。
Determining the parameters of heat and mass exchange between the coal pile and the air passing through it is of great importance in formulating new and perfecting existing methods of preventing internal fires. In order to study this problem, thermodynamic analysis was carried out on the experimental results of staff of Dongfang Coal Industry Institute of Safety Production. The laboratory is located in the 12-15 meters thick of Kalinin Coal Mine Management Office of Prokopyevsk Coal Union Company , Dip angle of 64 ~ 66 ° in the coal seam. In the three sections of 8 × 9 m ~ 2, 45 meters long in each chamber storage 2700 tons of coal, and make it to maintain the optimum air leakage in the coal spontaneous combustion conditions of the dynamic state.
