摘　　要：为正确分析新安煤田小浪底水库淹没区下煤炭资源安全开采的可行性,通过收集淹没区内二1煤层厚度、埋深、顶板岩性和库区水位、淹没范围、构造发育情况等资料,系统研究了淹没区范围内的地质、水文地质及工程地质条件,对水下开采的安全性进行了评价,分析认为,淹没区下开采时不但能留设足够的防隔水岩柱,而且在上覆岩层岩性组合、开采煤层埋深、构造发育情况、间歇性淹没区等方面存在利于水下煤炭开采的条件。In order to analyze the feasibility of underwater mining security in Xiaolangdi reservoir, geology, hydrogeology and engineering geological condition had been studied based on collecting information of coal seam thinkness, buried depth, lithology of roof, water level, inundated area structure development, and mining safety had been evaluated. The results show that not only the enough rock pillor thickness above the coal seam after mining, but also the the characteristics such as lithological association, burial depth, structure development, intermittent inundated area etc. be conducive to underwater mining in research areas.
