协同采矿方法协同度测度评价研究

Study on Measure Evaluation of Synergy Degree of Synergy Mining Methods

协同采矿方法的协同度测度评价一直是采矿工程学术界悬而未决的科学问题。将采矿方法划分为由3层子系统构成的系统结构,在此基础上绘制了协同采矿方法参与协同要素的结构型式图。通过引入协同熵概念,构建了协同采矿方法协同度测度评价模型。基于改进的层次分析法和熵权法,给出了协同采矿方法各子系统协同度评价指标赋权方法。参照系统协同度等级划分标准,以电耙—爆力协同运搬伪倾斜房柱采矿法为例,阐述了协同熵评价模型的运用流程,并对近10 a来我国学者发明的19种协同采矿方法的协同度进行了统计分析。研究表明:构建的协同采矿方法协同要素的结构型式图,能够清晰地表明各要素间或要素内的协同关系与工艺环节间的结构关系;样例协同采矿方法整体处于基本协同状态,其中采场回采工作、采场结构、落矿及矿石运搬等工作分别处于良好协同、轻度不协同和高度协同状态;19种协同采矿方法中,有8种、7种及4种整体处于基本协同、良好协同及高度协同状态。研究成果可为协同采矿方法的技术水平评价提供参考。

The measure evaluation of synergy degree of synergy mining methods has been an unsolved scientific problem in mining engineering.Mining methods were divided into the system structure of three-layer sub-system,and on this basis,the structure pattern graph of the synergy elements in the synergy mining method was drawn.A measure evaluation model of synergy degree of synergy mining methods was created by introducing the concept of synergy entropy.Based on the revised analytic hierarchy process and entropy weight method,the weighting method of each subsystem’ s synergy degree evaluation index was determined.According to the classification standard of the system synergy degree,the application process of the synergy entropy evaluation model is comprehensively illustrated with the example of pseudo-inclined pillar mining method for combined operation of electric rake and blasting force,and the statistical analysis of the synergy degree of the 19 synergy mining methods invented by Chinese scholars in the recent decade was made.The study results show that the structure pattern diagram of the synergy elements in the synergy mining method clearly shows the synergy relations among the elements and the structural relations among the technological links.The sample mining method is generally in the state of a basic synergy,in which stope mining,stope structure,ore removal and ore transport are in the states of good synergy,slightly unsynergy and highly synergy respectively.Among the 19 synergy mining methods,8 are in a basic synergy state,7 are in a good synergy state and 4 are in a highly synergy state.The above discussion results can provide reference for the evaluation of technical level of synergy mining methods.
