多层次模糊综合评判法在矿井断层预测中的应用
THE COMPREHENSIVE ASSESSMENT OF MULTIGRADE FUZZY IN APPLICATION TO THE FORECAST OF FAULT IN COAL MINE
【摘要】 本文针对影响煤矿生产最为严重的断裂构造,运用模糊综合评判思想,模拟了“专家”预测经验。首先指出断层形成和分布具有的模糊性,论证了模糊理论解决矿井断层的必要性和可行性;其次以白皎井田为例,讨论了模糊论域、权重及评语集等参数的选择,并得出矿井断裂预测中隶属函数的建立方法以及断裂构造的模糊综合评判模型;最后在矿井内进行了复杂程度等级的块段划分,取得较好成果。该方法也可推广到综采地质条件分类中。
【Abstract】 Employing the concept of fuzzy comprehensive assessment,according to the fault structure essentially effecting on the coal mine production, the paper imitates the specialists’ experience in forecast. Firstly, it is pointed out that the formation and distribution of faults are of fuzzy properties and the necessity and practicability to solve the mine faults with the fuzzy theory are demonstrated. Secondly, taking Baijiao Coal Mine as an example, the choice of the fuzzy discourse scope, proportion and assessment set etc. is discussed, and then the setting method of the subordinate function for forecasting the faults in coal mine and the mo- del of fuzzy comprehensive assessment in the fault structure are obtain- ed. Finally, according to the various grades in complexity, the mine is divided into different parts and the better result is gained. This methed can also be applied to the subdivision of geological condition in coal mine where the synthetic mining machines are used.
