基于灰色系统理论建立了综采工作面作业环境聚类指标体系。从人对作业环境的适应度出发,确定不同作业环境灰类的灰数,从而给出不同灰类的白化函数。利用现场实测环境参数,根据灰色熵权分析给出各指标信息熵,计算出各指标的聚类权,最后计算出各对象对应的聚类系数,确立了作业环境状况。
Based on the gray system theory, the working environment clustering index system of fully mechanized coal mining face was established. Starting from the adaptability of people to the working environment, the gray numbers of gray scales in different working environments are determined, and the whitening functions of different gray types are given. According to the measured environmental parameters in the field, the entropy of each index is given based on gray entropy analysis, and the clustering right of each index is calculated. Finally, the clustering coefficient of each object is calculated and the operating environment is established.
