简介:院吾祠煤矿构造复杂,断裂发育,严重制约了煤田的勘探与开发,通过野外地质工作和煤田勘探资料,对吾祠煤矿构造特征及对煤系地层的影响进行深入的探讨。结果表明吾祠煤矿构造复杂,断层与褶皱、断层与断层之间相互切割、相互作用,使煤系地层形态遭受破坏,平面上形成形态各异的断块,剖面上又组合为半地堑式及阶梯状抬斜断块等形式,破坏了煤层的连续性;缓倾角断裂使煤层重复出现,造成储量相对集中,含煤密度提高;同时由于断层的切割,造成煤系地层断失变薄,使主采煤层的埋深抬高;断裂活动和岩浆侵入,使煤的变质程度出现南西与北东分带的特点,由南西往北东变质程度逐渐变高,在断裂带及褶皱弯曲部位的变质程度较大。
简介:摘要本文通过新测制个旧地区把南组(T3b)剖面(共计2900米)与云南省地质局1970年测制的鸟格组(T3n)剖面的对比发现,认为鸟格组地层应归属到把南组地层内,而把南组地层岩性显示为浅海相,沉积方向由上层至下层。AbstractInthisarticle,throughcomparingthenewmeasuredBananFormation(T3b)profile(2900metersintotal)inGejiu,YunnanwiththeNiaogeFormation(T3n)profilemeasuredbygeologicalsurveyinyunnanprovincein1970,thispaperfoundthatNiaogeFormationbelongedtotheBananFormation,andthelithologyofBananFormationlayershowedaneriticfacies,sedimentarydirectionfromuppertolower.关键词云南个旧;剖面;岩性;对比KeywordsGejiu,Yunnan;profile;lithology;comparison

简介:摘要:论文 分析了黄花滩铁矿区构造承压含水层(带) 的地质、 水文地质条件,详细分析研究了矿区 地下水的赋存 条件、地下 水化学特征 。基本查明 了矿区构造承压含水层(带) 的水文地质条件及 成因机制,通过 对其 水文地质条件及 成因机制 的深 入分析 研究,为后期矿山开发设计利用提供了水文地质条件参考依据,同时也为该类型矿区水文地质条件调查、勘查和供水水源地的勘查工作起到了借鉴指导意义。 summary : T his paper analyzes the geological and hydrogeologic conditions of the structural confined aquifer ( zone ) in Huanghuatan i ron m ining a rea, and analyzes in detail the occurrence conditions and chemical characteristics of the groundwater in the mining area. The hydrogeologic condition and the genetic mechanism of the structural confined aquifer (zone) in the mining area are basically ascertained, and the hydrogeologic condition and the geological conditions are provided for the later mine development and design by the in-depth analysis of the hydrogeologic conditions and the genetic mechanism. At the same time, it also has a reference significance for the investigation of hydrogeological conditions, and the exploration of water supply sources in this type of mining area.
