煤矿井下动力现象的分类研究

STUDY ON THE CLASSIFICATION OF DYNAMIC PHENOMENA IN COAL MINE

分析了不同的介质和作用力对井下动力现象的影响，指出介质是产生各种动力现象的物质基础，力是产生动力现象的原因，介质和力当中任何一种因素发生变化，都会影响所产生的动力现象的属性和特征．据此，提出了按介质和力进行井下动力现象分类的标准，根据各种动力现象的作用力和介质，将其分为5个大类和10个小类．这对于指导井下动力现象的防治是非常有用的．图1。

The influence of different mediums and forces on the dynamic phenomena is analysed, It is pointed that mediums are the meterial base of all kinds of dynamic phenomena which occur in coal banes; forces are the reason which result in these dynamic phenomena. If one factor of them changes, the prOPerty and characteristic of dynamic phenomenon will change too. For this reason, The standard to classify dynamic phenomena in coal mine on the basis of forces and mediums is presented. According to the applied force and medium in every dynamic phenomenon of ed mines, all dynamic phenomena in coal Annes are classified into five categories which are composed of 10 sorts, Which are useful in guiding how to prevent and treat the dynamic phenomena of coal mines. 1fig., 10refs.
