As a large gold deposit in the northwest of Jiaodong peninsula, Dayingezhuang gold deposit is an altered rock-control gold deposit in fracture zone.The zoning of structural alteration of this deposit is important to the deep peripheral prospecting of deposits in the northwest of Jiaodong.This study presents the zoning of structural-alteration, the petrogenesis, geochemistry, and calculation of tectonic stress, to reveal the structural geochemistry and structural physicochemical process of structural alteration of the Dayingezhuang gold deposit.From the distal ore surrounding rock to the ore body:（1）the zonation pattern of structural alteration is weakly potassic alteration granitic rock → strongly potassic alteration granitic rock → phyllic and potassic alteration granitic rock → beresite;（2）The paleotectonic differential stress have an increase trend;（3）Si, Na, Ba and Srwaslost, K,Fe, Cu, Zn and Pb was externally supplied, and Au increased steadily in the whole mineralized process.The content of elements has a slight varies from unaltered rock to weakly potassic alteration granitic rock, with large amplitudes of variations from strongly potassic alteration granitic rock to beresite.During the mineralization process, the tectonic stress field and the migration of chemical compositions from rocks often display coupling behavior, as fracture and extensive space are often well developed within the rocks during the sericitization due to the relatively large paleotectonic differential stress, and this process is combined with the large variation in its compositions associated with intensive hydrothermal activity; all these factors together facilitate mineralization.

The Linglong gold field is located in the eastern part of the Linglong magmatic core complex of Jiaodong area, which is a set of rock mass combinations with complicated genesis, multiple sources and different magmatic evolution sequences surrounded by the Jiaojia fault belt and the Zhaoyuan-Pingdu fault belt.In the ore field, The core of the complex rock mass is formed by Linglong-type gneiss-like biotite granite and Guojialing-type porphyryite-like diorite, and the upper cover is Luanjiahe-type coarse-grained monzonitc granite and a small amount of Archean metamorphic rocks.The detachment belt is developed between the Linglong-type gneiss-like biotite granite pluton and the Luanjiahe-type coarse-grained monzonitc granite pluton which was formed by the progressive deformation and transformation of the Potouqing fault belt.The Potouqing detachment belt is a steep and slow shovel-type fracture, the depth in turning end of which is between-300 m and-500 m, and the turning depth of the detachment belt towards the north and east directions is gradually deepening.In order to understand the structural evolution and mineralization characteristics of the uplift detachment belt of the Linglong magmatic core complex, the observation results of the diagenetic structure and brittle ductile deformation characteristics of granite in the later stage show that the fault structure has undergone multiple stress turns from compression shear in the early stage of mineralization to extension detachment during the mineralization period. The diagenetic age（130～125 Ma） of the Guojialing-type porphyry-like diorite in the ore field is coincided with the plastic deformation stage of the detachment belt（137～123 Ma）,and the brittle deformation stage of the detachment belt（123～108 Ma） is basically coincided with the large-scale mineralization event（125.8 ～105 Ma） of the mine, showing the significant correlation between the structural mineralization of the magmatic core complex uplift-detachment belt in the Linglong gold field and the uplift structure of the porphyry-like granodiorite of the Guojialing type.The geometric, kinematics and chronological characteristics of the magmatic core complex uplift-detachment belt of Linglong gold field demonstrate the structural ore-controlling regularity, which can be used to guide the deep prospecting of Linglong gold field.

环境地质灾害属于自然灾害中十分重要的一种类型,环境地质灾害的发生对人们的生命安全及财产安全均会造成严重的影响及危害,有效防止环境地质灾害也就十分必要,在维护社会安全稳定方面具有重要的意义及价值.为能够有效避免环境地质灾害的发生及危害,相关人员应当对环境地质灾害现状加强认识,并且要提出相关有效措施进行防治,从而使环境地质灾害发生的可能性降低,使人们的生命财政安全得到更好的保证.

矿区水文、工程、环境地质工作是矿产勘查中一个重要的组成部分,同时也是评价矿床开采技术条件的依据.它直接关系到矿产资源的经济合理开发和矿山生产的安全、环保.水工环地质资料是正确评价矿床开采技术条件不可缺少的依据,同时还影响到矿床开发利用过程中可能发生的突发性地质灾害或安全事故的处理决策问题及矿山地质环境恢复治理方案的制订和实施.因此矿区水工环地质工作的程度和精度,势必影响到整个矿区的评价和矿床的合理开发利用及规划.

随着我国经济的不断发展,我国的水利工程也在不断电发展,每年的施工数量也在不断增加,在进行的施工过程中由于位置较为偏远,施工的的测量有着一定的难度,所以GPS-R TK技术被运用到施工的测量之中,本文主要就是论述基于GPS-R TK技术的施工的测量方法研究。

我国是一个地大物博的矿产资源国家,采矿业有着悠久的历史,长年以来采矿业为我国的经济发展做出了不可忽视的重要贡献。不过我们也是清晰的认识到了在发展经济的同时也给我们生活环境带来了很大的伤害,在面对这样的环境危机,我们必须要寻找更好的采矿作业的发展思路。怎样可以更好的进行采矿作业是各个矿区追求的一个重要方面,本文针对于采矿环境再造进行探讨,研究新的采矿技术。
