Research on the Permeability Characteristics of

The influence of mining method tunnel construction on the groundwater environment is a very important and complex engineering environment problem, and the strong differential weathering of water-rich granite strata increases the difficulty of this problem. In this paper, the mineral composition and microstructure characteristics of granite with different weathering degrees before and after the ...

How Does Being Near a Granite Mine Impact Real

When granite companies propose opening a quarry or a mine, environmental issues often top the list of local worries. Granite mining uses water for hydraulic drilling and to keep dust down. The water can wash mine waste into local waterways, affecting fishing and drinking water and putting heavy demands on the area water supply.

Effects of Cyclic Heating and Water Cooling on the ...

This paper aims to study the effect of cyclic heating and flowing-water cooling conditions on the physical properties of granite. Ultrasonic tests, gas measured porosity, permeability, and microscope observations were conducted on granite after thermal treatment. The results showed that the velocity of P- and S-waves decreased as the number of thermal cycles increased.

2020-6-1  For the hard crystalline rock like the Pocheon granite used in this study, we think water saturation has little influence on either cementation of minerals or strengths of minerals themselves. Therefore the UCS and elastic properties for this rock can show insignificant change after the water saturation. 3.3. Brazilian tensile strength
