摘要
通过过去实践工作资料的收集及科学分析,对相山矿田主要围岩类型、分布规律、地质特征等若干问题进行初步探讨。通过一些代表性的实例,说明矿体围岩受风化、蚀变、构造作用等的影响程度不同,其岩石工程地质性质相差很大,从而对开采中产生的岩石工程地质问题提出了建议。同时,以RQD值的测量及计算方法为例,对相山地区水文地质勘查实践工作提出相应的建议以及对勘查过程中的若干问题进行初步研究,认为RQD值的统计要考虑工作区的实际情况。
Through the collection and scientific analysis on the data of the past practice,some problems,such as the major surrounding-rock types,distribution regularities and geological characteristics in Xiangshan orefield, were discussed. With several representative examples,the varying degrees influence of the surrounding rocks experiencing weathering,alteration and tectonic effect were illustrated,and the rock engineering geological properties varied greatly,thus suggestions to the rock engineering geological problems in the process of exploiting were put forward. At the same time,taking the methods of measurement and calculation of RQD value as an example, the corresponding operating methods on the hydrogeological exploration practice in Xiangshan area were put forward,and some problems on the exploration process were preliminarily studied. It was thought that the statistics of RQD value depended on the actual situation of work area.
