Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below.

[0036] as attached figure 1 As shown, a construction method for a high slope of more than 100m with zero distance from the national highway includes the following steps:

[0037] Step 1, stockyard mining plan formulation;

[0038] Step 1.1, stockyard mining division, the stockyard mining area is divided into the main mining area and the reserved rock mass belt mining area;

[0039] Step 1.2, calculation of blasting parameters, predetermined blasting slag avalanche direction and main blasting slag rolling direction, wherein the main blasting slag should be prevented from rolling onto the national road;

[0040] Step 2. Set up blasting slag rolling protection device;

[0041] Step 2.1, the mining face of the main mining area is provided with protective belts at intervals of 20m to block rolling stones, forming multi-level protection;

[0042] Step 2.2, setting up a penetrating protectiv...

Abstract

The invention discloses a construction method for a high slope of more than 100m with zero distance from the national highway, comprising the following steps: step 1, formulation of stockyard mining plan; step 1.1, stockyard mining partition; step 1.2, blasting parameter calculation; step 2, Set blasting slag rolling protection device; step 2.1, the mining face of the main mining area is provided with protection belts at intervals of 20m to stop rolling stones; step 2.2, set up a penetration protective steel mesh on the upper edge of the excavation slope of the national road itself; step 2.3, Set up protective steel sheds for the national road area within the mining range of the stockyard; step 3, stone storage; step 4, set up a temporary detour route for the national road; step 5, mining construction in the stockyard. The construction method for the high slope of more than 100m at zero distance from the national road can simultaneously ensure the smooth passage of the national road and the normal mining of stone materials.

Description

technical field [0001] The invention belongs to the technical field of ultra-high slope construction, and in particular relates to a construction method for a high slope of more than 100m with zero distance from a national highway. Background technique [0002] During the construction process of mining stone on the high slope close to the national road, since the stockyard is close to the national road, it is necessary to meet the needs of the national road and to ensure the normal mining of the stockyard. Therefore, the construction has caused certain difficulties. [0003] For example, the Chinese invention patent document with the application number 200910063420.3 discloses a time-space conversion mining method for a high and steep rock slope stockyard in Linjiang, which includes the following steps: a. First, in terms of time, using the terrain folds on the mountainside, Along the river direction of the strip stockyard, the slag cutting tank (1) is excavated in advance t...
