The main method for predicting water inrush from coal seam floor and evaluating the water inrush degree of coal mining with water pressure is water inrush coefficient method.
煤层底板突水在我国华北型煤田矿井采煤过程中经常发生。
Firstly a main controlling factor system of coal floor water bursting has established,acquired and normalized main controlling factor data to establish thematic layers through GIS;then put to use of AHP to determine weighted percentage of each main controlling factor,on this basis,coal floor water bursting vulnerability zoning scheme put forward.
为解决开滦赵各庄十三水平的12煤层底板突水评价难题,引用了GIS的AHP型脆弱性指数法,即首先建立煤层底板突水主控因素体系,并通过GIS对主控因素数据进行采集及归一化处理,建立子专题图层,然后运用AHP法确定各主控因素的权重比例,在此基础上提出煤层底板突水脆弱性的分区方案。
In order to eliminate local protuberance of cold rolled coil caused by defect profile of cold rolled strip,inherited from defect profile of hot rolled strip,a new cosine contour of hot rolling work roller was presented based on the analysis of defect profile of hot rolled strip caused by feline ear type of roller wear to control edge thickness and local high point of hot rolled strip.
为解决由热轧带钢不良断面形状遗传到冷轧带钢而引起的钢卷局部突起缺陷,在分析猫耳形磨损辊型对热轧带钢断面形状不良影响的基础上,提出了以抑制热轧带钢边部增厚和局部高点相对高度为目的的工作辊余弦辊型。
