【摘要】 夹沟铝矿矿区位于河南省偃师市府店镇境内,其边坡由复杂多变的岩土介质组成,再加上曾经被盗采,内部存在采空区。本文对河南夹沟露天铝土矿边坡进行稳定性分析,将涉及工程地质学、岩土力学和相关学科的知识。 本文以河南夹沟露天铝土矿矿区边坡为研究对象,通过现场的勘探调查,了解其工程地质和水文地质条件,并在现场进行土力学试验且采取岩石试样,回校进行室内常规岩石力学试验,对试验得出的物理力学参数进行工程处理,以选取合理计算参数对边坡进行稳定性分析;再利用河南夹沟露天铝土矿矿区原有的采空区物探测量研究资料,准确了解采空区情况,运用岩石力学理论进行岩石结构承载力计算,确定最佳的设备作业的安全项板厚度。最后设计河南夹沟露天铝土矿矿区边坡的监测方案,对边坡的稳定性进行长期的监测,以保证河南夹沟露天铝土矿矿区安全开采。更多还原

【Abstract】 The Jiagou Aluminum Mining Area lies in the boundaries of town of shop of municipal government of Yanshi of Henan Province. The slope is made up of complicated and changeable rock soil medium, and because it is exploited once, there is the empty district inside the slope.This paper about the Jiagou open-pit slope stability analyse , will relate to engineering geology > rock soil mechanics and relevant disciplines.This paper makes the slope of the Jiagou open-pit mining area in Henan as the research object.We investigate through the exploration of the scene , understand its project geology and hydrology geological condition, and carry on the soil mechanics test and adopt the rock sample at the scene.When we go back to the school ,the routine rock mechanics test is carried on in the room.In order to choose reasonable calculation parameter to go on slope stability analyse, the rock physics mechanics parameters have been obtained by laboratory and optimized by empirical formula. Then we utilize the ditch materials of empty district, understand accurately the empty district situation, and use the theory of mechanics of rock to calculate the bear strength of rock structure ,confirm the security roof thickness of the best equipment homework. Finally the paper designs the monitoring scheme of the slope by the Jiagou open-pit mining area in Henan, for carrying on long-term monitoring with the stability of the slope, so as to we ensure that the Jiagou open-pit mining area in Henan can be exploited safely.更多还原
