摘要
为提高卡房采选厂巷道掘进效率,在对巷道掘进各个工序进行调查的基础上,应用不定型的Laplace等可能性准则对巷道掘进的各个工序所需时间进行了分析,找出影响掘进效率的主要因素——凿岩爆破和出渣,并通过改进掏槽布孔方式及装药量等,达到了提高巷道掘进效率的目的。
In order to improve the efficiency of heading advance in Kafang Mine, Based on the investigation of working procedures of heading advance in Kafang Mine, the time need by each working procedure of heading advance is analyzed using Laplace＇ s principle -of- insufficient -reason criterion, the main factors affecting the efficiency of heading advance am fount out, they are drilling and blasting and muck removing, Through improving the pattern of borehole layout and explosive charge of borehole, the purpose of improving efficiency of heading advance has been reached.
