21146.黃陵彬長(zhǎng)礦區(qū)地下水賦存規(guī)律研究

1、論文題目：黃陵彬長(zhǎng)礦區(qū)地下水賦存規(guī)律研究專業(yè)：礦產(chǎn)普查與勘探碩士生：穆鵬飛（簽名）指導(dǎo)教師：王英（簽名）王新（簽名）摘要黃陵彬長(zhǎng)礦區(qū)是陜西省重要的煤炭工業(yè)基地，隨著煤礦開采，水害問題日益突出，生產(chǎn)用水以及居民生活用水需求量也逐漸增大，研究礦區(qū)地下水的賦存規(guī)律，對(duì)礦井生產(chǎn)、人民生活有實(shí)際的指導(dǎo)意義。本文通過對(duì)黃陵彬長(zhǎng)礦區(qū)地質(zhì)勘探資料、水文觀測(cè)資料及氣象資料的系統(tǒng)分析，研究黃陵彬長(zhǎng)礦區(qū)以白堊系下統(tǒng)洛河組含水層為主的地下水賦存基本特征，總結(jié)了

2、地下水的賦存規(guī)律，劃分了水文地質(zhì)單元。得出以下主要結(jié)論：（1）洛河組頂?shù)装褰Y(jié)構(gòu)特征控制著地下水垂向補(bǔ)給、側(cè)向徑流的特征，起伏狀態(tài)控制著地下水在較大向斜軸部出現(xiàn)強(qiáng)富水區(qū)域；（2）洛河組厚度決定含水層富水性，隨著洛河組含水層厚度的增加，富水性有增強(qiáng)的趨勢(shì)；（3）黃陵彬長(zhǎng)礦區(qū)共劃分出兩個(gè)一級(jí)水文地質(zhì)單元，四個(gè)二級(jí)水文地質(zhì)單元。在此基礎(chǔ)上，選取水文地質(zhì)條件典型的、且相對(duì)獨(dú)立的區(qū)域進(jìn)行地下水流模擬，建立水文地質(zhì)概念模型，選用VisualModfl
