Roof water inrush is a complicated process of geology and mechanics, it concerned with the style, character and conservation of water bodies, and with hydrogeologics, stratum structure and geological mining conditions of roof water resisting layer. There are various factors which influence the process. Each factor is quantified using the subjection function of fuzzy synthesis methods. So, quantified values are obtained. Finally, an evaluation of roof water inrush grade is performed according to principle...

Roof water inrush is a complicated process of geology and mechanics, it concerned with the style, character and conservation of water bodies, and with hydrogeologics, stratum structure and geological mining conditions of roof water resisting layer. There are various factors which influence the process. Each factor is quantified using the subjection function of fuzzy synthesis methods. So, quantified values are obtained. Finally, an evaluation of roof water inrush grade is performed according to principle of fuzzy conversion and maximum subjection degree. Foundation for making water proofing diversion measurement and arranging water proofing diversion project also has been provided.

矿井顶板水的涌出不仅与含水体本身的水体类型、特征、赋存条件有关 ,而且还与煤层顶板各隔水岩层的水文地质条件、地层结构及采矿地质条件有关 ,是一个十分复杂的地质力学作用过程 ,其影响因素是多方面的 .运用模糊评判中的隶属度函数对各因素进行量化 ,得出涌水等级评价的量化指标 ,最终应用模糊变换原理并依据最大隶属度原则 ,进行顶板涌水等级评价 ,为矿井制定防排水措施、安排防排水工程提供依据 .

Through integrated analysis of T2195 working face roof water inrush water quality examination, periphery mining situation, the authors are of the opinion that the T2195 face water inrush is mainly from roof water of No.5 coal seam, water from ground grouting is only one kind of indirect intake. Thus a suggestion of proceed with ground grouting put forward, further consummation of underground drainage system and other water control measures are needed to keep high yield and high efficiency of the working face.
