【摘要】：注浆是治理矿井涌（淋）水的主要手段，传统的注浆工程往往忽视对水文地质的研究，，盲目注浆堵水，缺乏针对性，遇到深大断裂破碎带、地下岩溶（Karst）径流带甚至溶洞时，即使消耗大量浆液材料，效果却未必明显。电法具有成本低、速度快、灵敏度高等特点，在水文地质勘察中有着极好的应用前景。论文受到“超深竖井注浆堵水关键技术研究”项目的资助，依托校企合作项目“鸟山煤矿立井综合注浆技术研究”，采用工程应用与理论分析相结合的方法开展电法在深部矿井地下水勘察中的应用研究。以鸟山煤矿风井、副井为例，运用不同的电法勘探方法分别对两个立井进行勘察，将探测数据解译，验证其地质特征，并说明主要含水层（段）位置和地下水的类型、分布状态、相互联系等情况，指导注浆方案的制定，达到服务该矿区正常矿井建设和生产的目的。在此次应用中，风井地下水勘察采用的是激发极化法，副井采用矿井瞬变电磁法和天然场源SYT法相结合的综合探测方法，三种方法各有特点。在进行勘探工作前，作者整理了大量前人关于鹤岗煤田及鸟山矿区的地质构造、规律性研究等地质资料，这些正是后期勘探成果解释的基础。通过分析研究，旨在证明电法在深部矿井地下水勘察中具有较高的灵敏度和较强的实用性，在结合测区地质构造特征的基础上，解译探测成果，结果与实际情况较吻合，为矿井防治水工作提供可靠地质保障。
[Abstract]:Grouting is the main means of controlling mine water. Traditional grouting projects often ignore the study of hydrogeology, blindly grouting water shutoff, lack of pertinence, encounter deep and large fracture zone, underground karst (Karst) runoff zone or even karst cave. Even if a large amount of slurry materials are consumed, the effect is not necessarily obvious. Because of its advantages of low cost, high speed and high sensitivity, the electric method has an excellent application prospect in hydrogeological survey. This paper is supported by the project "Research on key techniques of grouting and plugging Water in Super Deep Shaft", and relies on the project of "Comprehensive grouting Technology Research of Shaft in Yaoshan Coal Mine", which is a joint project between schools and enterprises. The application of electrical method in underground water exploration of deep mine is studied by combining engineering application with theoretical analysis. Taking the air well and auxiliary well of Yaoshan coal mine as examples, two vertical wells are surveyed by using different electrical exploration methods, the exploration data are interpreted, the geological characteristics are verified, and the location of the main aquifer (section) and the type of groundwater are explained. The distribution state and interrelation between each other guide the formulation of grouting scheme to serve the purpose of normal mine construction and production in the mining area. In this application, the method of induced polarization is used in the investigation of air well groundwater, and the integrated detection method of mine transient electromagnetic method and natural field source SYT method is adopted in the auxiliary well. Each of the three methods has its own characteristics. Before the exploration work, the author collates a lot of geological data about the geological structure and regularity of Hegang coalfield and Yaoshan mining area, which is the basis of the interpretation of the later exploration results. Through analysis and research, it is proved that the electric method has higher sensitivity and stronger practicability in the underground water exploration of deep mine. On the basis of combining the geological structural characteristics of the survey area, the results of the exploration are interpreted and the results are in good agreement with the actual situation. It provides reliable geological guarantee for mine water prevention and control.
