【摘要】：淮南煤田地處華北煤田南緣,經(jīng)歷多期構(gòu)造地質(zhì)作用,使區(qū)內(nèi)構(gòu)造地質(zhì)條件復(fù)雜。煤田主體為復(fù)式向斜構(gòu)造,區(qū)內(nèi)褶皺、斷裂構(gòu)造極為發(fā)育。構(gòu)造作用不僅控制了含水系統(tǒng)的結(jié)構(gòu)形態(tài),而且控制著地下水動力條件,特別是在喜山期形成的大量NE-NNE走向張裂性正斷層,在研究區(qū)形成階梯式斷裂構(gòu)造,對含水層改造最為明顯。因此,在本區(qū)開展構(gòu)造控水研究很有必要也很有意義。 本文以淮南煤田北部的口孜東礦、劉莊礦、謝橋礦和張集礦為研究對象,研究范圍涵蓋阜東礦區(qū)、潘謝礦區(qū)。運用構(gòu)造演化法和水文地質(zhì)結(jié)構(gòu)系統(tǒng)分析法,主要從淮南煤田區(qū)域構(gòu)造特征及構(gòu)造演化過程、構(gòu)造控水、水文地質(zhì)塊段劃分三方面進行研究,取得如下一些認(rèn)識： 1.構(gòu)造特征方面：淮南煤田現(xiàn)今構(gòu)造格局是印支運動、燕山運動、喜山運動等多期構(gòu)造運動疊加的結(jié)果,以NE-NNE向構(gòu)造數(shù)量最多,近EW向和NW-NWW向次之,研究區(qū)基巖面形態(tài)特征為東南高、西北低,是推覆構(gòu)造產(chǎn)生的褶皺經(jīng)差異性風(fēng)化的結(jié)果； 2.構(gòu)造如何控水：構(gòu)造控水可概括為“水文地質(zhì)結(jié)構(gòu)系統(tǒng)控制地下水系”,大型構(gòu)造運動如加里東運動、華力西運動控制著含水層的沉積和形成,后期又經(jīng)歷的多期擠壓和拉張作用對含水層加以改造,最終將各含水層改造成現(xiàn)今這種狀態(tài),斷層對含水層切割,增強了巖層的儲水能力和富水性,大型阻水構(gòu)造如阜鳳逆沖斷層,往往作為水文地質(zhì)單元邊界,而深大斷裂溝通了各含水層,控制著地下水的補、徑、排特征； 3.水文地質(zhì)單元塊段劃分：根據(jù)不同地段水文地質(zhì)條件及水動力條件的差異,將研究區(qū)劃分為“北區(qū)”塊段、“南區(qū)”塊段、“中區(qū)-西”塊段和“中區(qū)-東”塊段,并分析構(gòu)造對各塊段內(nèi)部的水動力條件的控制。 最后,結(jié)合礦山生產(chǎn)實際,總結(jié)了斷層對研究區(qū)礦井突水的控制作用,認(rèn)為突水部位往往在深大斷裂或次生斷層附近,深大斷裂及次生斷層部位為礦井水害隱患點,建議注漿改造。
[Abstract]:Huainan coalfield is located in the southern margin of North China coalfield, experiencing multiple tectonic geological processes, which makes the tectonic geological conditions in the area complicated. The main body of the coalfield is a compound syncline structure, and the fold in the area, The tectonic process not only controls the structural shape of the water-bearing system, but also controls the dynamic conditions of groundwater, especially in the Himalayan period, where a large number of NE-NNE strike fracture normal faults are formed, and a stepped fault structure is formed in the study area. Therefore, it is necessary and meaningful to study tectonic water control in this area. In this paper, the Kou Zidong, Liuzhuang, Xieqiao and Zhangji mines in the northern part of Huainan coalfield are taken as the research objects. The research scope covers the Fudong and Panxie ore areas. The structural evolution method and the hydrogeological structure system analysis method are used in this paper. Based on the study of the regional structural characteristics and tectonic evolution process of Huainan coalfield, structural water control and the division of hydrogeological blocks, some understandings are obtained as follows:. 1. Structural characteristics: the present tectonic pattern in Huainan coalfield is the result of the superposition of Indosinian, Yanshanian and Himalayan movements, with the NE-NNE direction being the largest, the near EW direction and the NW-NWW direction being the second. The characteristics of the bedrock surface in the study area are high in the southeast and low in the northwest, which is the result of the differential weathering of the fold produced by the nappe structure. 2. How the structure controls water: tectonic water control can be summed up as "hydrogeological structure system controls groundwater system". Large tectonic movements such as Caledonian movement and Varisci movement control the deposition and formation of aquifers. At the end of the period, the aquifer was transformed by multiple periods of compression and tension, and eventually the aquifer was transformed into the present state, and the fault cut the aquifer, which enhanced the water storage capacity and water enrichment of the rock bed. Large water-blocking structures, such as Fufeng thrust fault, are often used as the boundary of hydrogeological unit, while deep and large faults communicate with each aquifer and control the characteristics of groundwater replenishment, diameter and drainage. 3. Block division of hydrogeological units: according to the differences of hydrogeological and hydrodynamic conditions in different sections, the study area is divided into "North" block, "southern" block, "central area-west" block and "central area-east" block. The control of the hydrodynamic conditions in each block is analyzed. Finally, combined with the practice of mine production, this paper summarizes the control effect of fault on water inrush in mine in the study area. It is considered that the water inrush part is usually near deep fault or secondary fault, and deep fault and secondary fault are hidden danger points of mine water hazard. It is suggested that grouting be reformed.
