为了预测和预防煤矿重大灾害,作者在现场以实验、测量为主,研究了集中监视环境的计算机技术(将与灾害有关的井下环境情报传到地面,并在地面进行集中监视)、监视项目之间的关系以及根据各自时间变化等预防灾害的程序。 为了早期发现自然发火,较为有效的方法是搜集危险地点的气体并加以分析,依此捕捉指标气体成分的容积比(以下称指标气体比),目前各煤矿均采用这种方法。然而,搜集气体是个很麻烦的问题,而且受气体取样、次数和场所的限制。另外,关于测定煤层内温度的方法目前仍未明确下来,一
In order to predict and prevent major disasters in coal mines, the author mainly focused on experiments and surveys in the field. He studied computer technologies for centralized monitoring of the environment (disaster-related underground environment information was transmitted to the ground and centralized monitoring was conducted on the ground) The relationship between them and the procedures for preventing disasters such as changes in their own time. In order to detect spontaneous combustion in the early stage, it is more effective to collect and analyze the gas in dangerous locations to capture the volumetric ratio of the index gas components (hereinafter referred to as index gas ratio). At present, all coal mines use this method. However, collecting gas is a troublesome issue and is limited by gas sampling, frequency and location. In addition, the method of determining the temperature inside the coal seam is still not yet clear
