煤矿井下环境马田系统评价模型及应用

MTS evaluation model of underground colliery environment and its application

由于煤矿井下环境复杂恶劣并伴随安全隐患,给井下工作人员带来很多不便。笔者通过对煤矿井下环境影响因素进行分析,选取可信指标并采用马田系统评价方法,对评价指标进行降维和优化,建立煤矿井下环境马田系统评价模型。实际应用验证了该评价方法对于煤矿井下环境分析的可行性,并提出改善煤矿井下环境的意见。

Since the complex and harsh environment of the underground colliery brings staff a lot of inconvenience and serious safety hazards, the analysis of factors affecting underground colliery environment appears to be important. After selecting creditable indexes, the paper took MTS （Mahalanobis-Taguchi System） evaluation method to reduce dimensionality and conduct optimization, so as to establish the MTS evaluation model of underground colliery environment. Actual application in a colliery of Shanxi province verified the feasibility of the evaluation method. Moreover, suggestions to improve the environment of underground colliery were proposed.
