The theory and method of extenics were applied to establish classical field matterelements and segment field matter elements for coal and gas outburst.A matter-element model for prediction was established based on five matter-elements,which includedgas pressure,types of coal damage,coal rigidity,initial speed of methane diffusionand in-situ stress.Each index weight was given fairly and quickly through the improvedanalytic hierarchy process,which need not carry on consistency checks,so accuracy ofassessment can be improved.

周二的早晨秋高气爽,我来到伦敦地标碎片大厦参加某投资公司新闻发布会。按照发布会邮件的内容,该公司的首席经济学家将畅谈近期国际经济波动的态势,颇有指点江山的豪气。冲着这内容,我8点半就到场了。  乘电梯直达31层的用餐区域,妆容精致笑容可掬的公司公关欢迎前来的采访人员。伦敦虽是国际都市,建筑却维持了中等的层高,31楼便足够饱览城市全景。采访人员们不由地惊叹窗外美景,寒暄起来,仿佛都忘了国际形势和经济
