Method for rectifying and reforming potential safety hazards in operation period of upstream type tailing pond

Abstract

The invention discloses a method for rectifying and reforming potential safety hazards in the operation period of an upstream type tailing pond. The method comprises the steps that a newly-built accumulation dam body and a percolate collection system are provided, wherein the accumulation dam body is composed of a first-stage stone-heaping dam and other stages of accumulation sub-dams, the first-stage stone-heaping dam is built on an existing initial dam, then the other stages of accumulation sub-dams are sequentially and newly built on the first-stage stone-heaping dam to the rectifying and reforming elevation, slag is heaped from the tops of the other stages of accumulation sub-dams to the tail of the pond according to a certain gradient, and the flood regulation storage capacity meetingthe flood control standard is reserved at the tail of the pond; and the percolate collection system is buried in a slag body in front of the pond and is composed of a longitudinal seepage drainage pipe and a transverse seepage drainage pipe, and the longitudinal seepage drainage pipe and the transverse seepage drainage pipe are arranged in a shape like a Chinese character 'wang' on the plane. Bymeans of the method, the problems that in the operation period of the upstream type tailing pond, slag is heaped from the tail of the pond to the front of the pond in a non-standard manner, the floodregulation storage capacity does not meet the requirement, and the potential safety and environment protection hazards and sustainable development of the slag heaping storage capacity cannot be sufficiently utilized can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of tailings ponds, and in particular relates to a rectification method for safety hazards during the operation period of an upstream tailings pond, which can be extended to similar projects such as domestic waste landfills. Background technique [0002] Tailings ponds are necessary production facilities for metal and non-metallic mining enterprises. Once an accident occurs after it is put into operation, it will definitely cause heavy losses to the safety of people's lives and property downstream. Therefore, ensuring the safety of tailings ponds has always been the focus of safety production work and difficulty. [0003] At present, domestic research on the safety operation and management measures of tailings ponds is mostly concentrated in the survey and design process, but there is little research on the management of the operation period and the subsequent rectification measures for potential safety hazar...
