Rock stability
Web11 Apr 2024 · As the rock stratum can form a certain support structure after fracturing, when J c increases to a certain extent, the influence of mining on the slope stability decreases sharply. Therefore, there is a non-linear negative correlation between n m and J c , and the rate of decay of n m decreases as the J c increase. Web13 Feb 2024 · Perilous rock instability on the soil slope brings a substantial threat to project operation and even people’s lives. The buried depth of the perilous rock is a challenge to deal with and primarily determines its stability, and the indirect rapid identification of its buried depth is the key to its stability evaluation. The paper aims to find a new and quick …
