【摘要】：淮南煤田位于華北煤田南緣,地質(zhì)條件復(fù)雜,礦山在開采過程中受到各種水害的威脅。隨著開采增加,底板灰?guī)r突水概率增大。系統(tǒng)開展水文地質(zhì)條件分析和地下水動(dòng)態(tài)特征研究,為礦山水害防治提供一定基礎(chǔ),對(duì)于煤炭安全開采具有十分重要的意義。 本文通過查閱相關(guān)文獻(xiàn),以潘謝礦區(qū)為研究對(duì)象,系統(tǒng)整理分析區(qū)內(nèi)水文地質(zhì)基礎(chǔ)資料,分析灰?guī)r地層、構(gòu)造地質(zhì)異常體形態(tài)特征、水文地質(zhì)條件、含水層的結(jié)構(gòu)、水文地球化學(xué)特征、地下水的補(bǔ)、徑、排特征,以及灰?guī)r地層之間的水力聯(lián)系,并利用區(qū)內(nèi)抽放水試驗(yàn)數(shù)據(jù),分析其富水性規(guī)律及影響因素等。 為進(jìn)一步弄清潘謝礦區(qū)灰?guī)r深部開采水文地質(zhì)條件,系統(tǒng)分析研究了張謝礦區(qū)和潘集礦區(qū)的水位、水質(zhì)、水溫等動(dòng)態(tài)特征及其影響因素。結(jié)果表明：潘謝礦區(qū)水文地質(zhì)補(bǔ)給邊界具有很好的隔水性,礦區(qū)復(fù)向斜內(nèi)部裂隙、斷層較發(fā)育,地下水徑流條件良好；且礦山開采期間補(bǔ)給量小于疏放量,消耗內(nèi)部存儲(chǔ)量；地質(zhì)構(gòu)造是影響灰?guī)r水動(dòng)態(tài)控制因素,而疏放則是地下水動(dòng)態(tài)變化外界誘發(fā)因素。
[Abstract]:Huainan coalfield is located in the southern margin of North China coalfield. The geological conditions are complex and the mines are threatened by various kinds of water hazards in the course of mining. With the increase of mining, The analysis of hydrogeological conditions and the study of groundwater dynamic characteristics are carried out systematically, which provides a certain foundation for the prevention and control of mine water hazards, and is of great significance for the safe mining of coal. By referring to relevant documents and taking Panxie mining area as the research object, this paper systematically arranges and analyzes the basic hydrogeological data, the limestone strata, the morphological characteristics of structural geological anomalies, the hydrogeological conditions and the structure of the aquifer. Hydrogeochemical characteristics, groundwater recharge, diameter, drainage characteristics, and the hydraulic relationship between limestone strata are analyzed. The water-rich law and influencing factors are analyzed by using the test data of pumping water in the area. In order to further understand the hydrogeological conditions of deep limestone mining in Panxie mining area, the water level and water quality of Zhangxie and Panji mining areas are systematically analyzed and studied. The results show that the hydrogeological recharge boundary in Panxie mining area has good water-repellent, the complex inclined internal fissure, the fault is relatively developed, and the groundwater runoff condition is good. During mining period, the recharge is smaller than the thinning amount, and the internal storage is consumed; the geological structure is the influence factor of limestone water dynamic control, and the thinning is the external inductive factor of groundwater dynamic change.
