Embodiment 1

[0018] A method for preventing and treating landslides in mines, said method comprising the following steps:

[0019] (1) Fixed isolation: Fix corrugated partitions or earth walls at the same contour line on the slope of the mine. The walls are fixedly connected by anchor rods, and the distance between adjacent anchor rods is 2 meters, the angle between the partition or earth wall and the mine slope is 60 degrees, and the partition or earth wall on the lower contour line is smaller than the adjacent one. The height of the partition or earth wall on the higher contour line is 5cm, and the depth of the partition or earth wall is 50cm;

[0020] (2) Opening water channels: Excavate earth pits every 3 meters at the bottom of the partition or earth wall, and excavate linear earth trenches between adjacent earth pits to connect with each other. The inner wall of the earth trench is 110 meters away from the mine slope degree angle, and the bottom surface of the soil ditch is in a con...

Embodiment 2

[0027] A method for preventing and treating landslides in mines, said method comprising the following steps:

[0028] (1) Fixed isolation: Fix corrugated partitions or earth walls at the same contour line on the slope of the mine. The distance between partitions or earth walls on different contour lines is controlled at 2 meters, and The walls are fixedly connected by anchors, and the distance between adjacent anchors is 3 meters, and the angle between the partition or earth wall and the slope of the mine is 75 degrees, and the partition or earth wall on the lower contour line is smaller than the adjacent one. The height of the partition or earth wall on the higher contour line is 10cm, and the depth of the partition or earth wall is 70cm;

[0029] (2) Opening water channels: Excavate earth pits every 5 meters at the bottom of the partition or earth wall, and excavate linear earth ditches between adjacent earth pits to connect with each other. The inner wall of the earth ditch...

Abstract

The invention discloses a mining landslide prevention treatment method which comprises the following steps: fixing and partitioning, dredging water channels, fixing rock, fixing slope bases, fixing poles and shaping slope surfaces. By adopting the mining landslide prevention treatment method, terrain characteristics of mine are sufficiently utilized, and with the combination of related fixing facilities, the slope surfaces of the mine are effectively transformed, hazard of mine landslide can be greatly avoided, relatively long long-lasting continuous time and reliability can be achieved, later maintenance cost can be reduced, the security coefficients of the mine are increased, and good economic benefits can be made for the mine.

Description

technical field [0001] The invention belongs to the field of mine management, in particular to a method for preventing and treating landslides in mines. Background technique [0002] In the process of mining, the stability of the slope directly restricts the safety of the mine, and is one of the most critical factors affecting the economic benefits of the mine. Generally, the impact of landslides runs through from the start of mine production to the end of mining. Therefore, the treatment of open-air slopes should continue until the end of mining, and the investment is huge. With the gradual increase of mining depth, the height, area, and maintenance time of the open-pit mine slope will increase correspondingly, otherwise, the slope disaster will become increasingly prominent. Therefore, the stability of slopes has increasingly become one of the key points of mine disaster prevention in my country. [0003] In the mining process, landslide is a major geological disaster. I...
