電法勘探在深井注漿工程前期地下水勘察中的應(yīng)用

發(fā)布時間:2019-01-21 16:27
【摘要】:注漿是治理礦井涌(淋)水的主要手段,傳統(tǒng)的注漿工程往往忽視對水文地質(zhì)的研究,,盲目注漿堵水,缺乏針對性,遇到深大斷裂破碎帶、地下巖溶(Karst)徑流帶甚至溶洞時,即使消耗大量漿液材料,效果卻未必明顯。 電法具有成本低、速度快、靈敏度高等特點,在水文地質(zhì)勘察中有著極好的應(yīng)用前景。論文受到“超深豎井注漿堵水關(guān)鍵技術(shù)研究”項目的資助,依托校企合作項目“鳥山煤礦立井綜合注漿技術(shù)研究”,采用工程應(yīng)用與理論分析相結(jié)合的方法開展電法在深部礦井地下水勘察中的應(yīng)用研究。以鳥山煤礦風(fēng)井、副井為例,運用不同的電法勘探方法分別對兩個立井進行勘察,將探測數(shù)據(jù)解譯,驗證其地質(zhì)特征,并說明主要含水層(段)位置和地下水的類型、分布狀態(tài)、相互聯(lián)系等情況,指導(dǎo)注漿方案的制定,達(dá)到服務(wù)該礦區(qū)正常礦井建設(shè)和生產(chǎn)的目的。在此次應(yīng)用中,風(fēng)井地下水勘察采用的是激發(fā)極化法,副井采用礦井瞬變電磁法和天然場源SYT法相結(jié)合的綜合探測方法,三種方法各有特點。在進行勘探工作前,作者整理了大量前人關(guān)于鶴崗煤田及鳥山礦區(qū)的地質(zhì)構(gòu)造、規(guī)律性研究等地質(zhì)資料,這些正是后期勘探成果解釋的基礎(chǔ)。 通過分析研究,旨在證明電法在深部礦井地下水勘察中具有較高的靈敏度和較強的實用性,在結(jié)合測區(qū)地質(zhì)構(gòu)造特征的基礎(chǔ)上,解譯探測成果,結(jié)果與實際情況較吻合,為礦井防治水工作提供可靠地質(zhì)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.
