| Abstract: |
| For the rock slope of an open pit mine, the indoor point load test of the rock is carried out by on-site sampling, and the point load intensity value of the limestone in different areas of the open pit slope is calculated and analyzed. At the same time, according to the point load test results, the relationship between the strength index and the compressive strength can be used to convert the uniaxial compressive strength of limestone in different areas of the open pit slope. Furthermore, the variation law of the uniaxial compressive strength of the limestone in the elevation, north-south direction, east-west direction and the same elevation direction is analyzed. It also provides a certain data basis for understanding the mechanical properties of limestone in this region. |
