AI Technical Summary

Technical Problem

Existing technologies lack quantification of stability when selecting geosynthetic materials for closure and covering systems, and fail to reduce the load on the lining system, leading to easy slippage and damage, which affects environmental protection.

Method used

By identifying the contact surfaces with potential slippage instability in the enclosure and covering system, the allowable tensile strength of geosynthetics of different specifications is calculated. The double-wedge method is used to calculate the anti-slip stability safety factor, which is then compared with the standard safety factor to select the material specifications that meet the stability requirements.

Benefits of technology

This achievement enables the quantification of the stability of the field closure system, provides a more scientific basis for material selection, reduces the risk of slippage and instability, and ensures the safety and environmental protection of the system.

Abstract

This application discloses a method and apparatus for selecting geosynthetics based on the stability of a mine waste rock dump closure system, relating to the field of mine waste rock dump closure technology. It quantifies the stability of the closure system into a more reasonable anti-slip stability safety factor, providing a more scientific basis for geosynthetic material selection for the closure system. The method includes: determining the main tensile geosynthetics affected by the target contact surface; selecting at least two specifications of geosynthetics as candidates based on the characteristic indicators of the main tensile geosynthetics, and calculating the allowable tensile strength of different specifications of geosynthetics; calculating the anti-slip stability safety factor of the closure system using different specifications of geosynthetics using the double-wedge method; and comparing the anti-slip stability safety factor of the closure system using different specifications of geosynthetics with a standard safety factor to select a geosynthetic material specification that meets the stability requirements of the closure system.
