一、分 类 原 则 在开采瓦斯煤层时,经常发生一些外表很相似的与瓦斯有关的动力现象,人们往往通称之为“突出”。因为它们都是事先没有预计到的,并且伴随涌出大量的瓦斯(沼气或二氧化碳)而造成一定的动力效应。然而,这些动力现象的本质并不相同。应该予以正确的分类,并采取不同的预测和预防方法。 各个研究者提出不同的分类方法,但大都倾向于按动力现象的成因分类。 例如,还在三十年代,苏联斯柯琴斯基就提出了分类问题,按照他的意见,突出可分为5类,即:
First, the principle of classification In the mining of coal seams, there are often appearance of similar gas-related power phenomenon, people often referred to as “prominent.” Because they were not predicted in advance and caused a certain amount of dynamic effects with a large amount of gas (methane or carbon dioxide). However, the nature of these dynamics is not the same. Correct classification should be adopted and different methods of prediction and prevention should be adopted. Various researchers propose different classification methods, but most of them tend to be classified according to the causes of dynamic phenomena. For example, in the 1930s, the Soviet Union, Schukenszki, put forward the classification problem. According to his opinion, the outstanding can be divided into five categories:
