Opencast coal mine working side landslide treatment method based on reduction of production influence degree

Abstract

The invention provides an opencast coal mine working slope landslide treatment method based on reduction of production influence degree, which comprises the following steps: S1, on-site reconnaissance: setting an initial warning line according to the on-site reconnaissance situation to ensure normal production of adjacent working faces without influencing the production schedule; s2, performing engineering exploration, performing on-site sampling to perform a rock physical experiment, and determining the geological condition of a landslide area; s3, arranging monitoring lines in the landslidearea, and conducting ground surface and deep deformation monitoring on the landslide area; s4, predicting a potential slip trend to determine a landslide influence range, and setting a warning area again for the landslide influence range to determine a production area; by accurately determining the minimum range of the landslide influence, the strippable area of the working side is maximized, theinfluence time and influence range of the landslide are minimized, and on the premise of safety, normal stripping operation is not influenced, the coal exposing speed is increased, the coal mining amount is guaranteed, the production task is completed, and the emergency disposal capacity of enterprises is improved. The influence degree of working side landslide on production is reduced.

Description

technical field [0001] The invention belongs to the technical field of landslide control in open-pit mines, and in particular relates to a landslide control method for working sides in open-pit coal mines. Background technique [0002] Open-pit mine sides refer to the overall composition of all the step slopes, flat plates (or platforms) and inclined pit lines around the mine, and working sides refer to the sides or parts of them that are composed of working steps and are being mined. Once a landslide occurs in the working gang, it will inevitably affect the stripping operation of the adjacent working face, thereby affecting the coal production speed, and further affecting the economic benefits of the enterprise for the month. [0003] At present, the prevention and control technology for dump slopes is very mature, but the prevention and control technology for dump slopes is not suitable for landslides where blasting, excavation disturbance, and workers and equipment are ev...
