Drag bucket forklift operating method

Abstract

An embodiment of the invention discloses a drag bucket forklift operating method. The drag bucket forklift operating method comprises the steps that a first operating platform is built on the stope; adrag bucket forklift is located on the first operating platform, pushes layered materials on a blasting muck pile to a waste dump in an overcast mode and pushes leading ditch materials to the waste dump in an overcast mode; the pushed layered materials on the blasting muck pile and the pushed leading ditch materials are combined to form a second operating platform on the waste dump; after the pushed layered materials on the blasting muck pile and the pushed leading ditch materials are completely pushed in an overcast mode, the drag bucket forklift constructs a connection channel for the second operating platform; the drag bucket forklift moves to the second operating platform; and the drag bucket forklift pushes the first operating platform and materials at the bottom of the first operating platform in an overcast mode. By the use of the drag bucket forklift operating method, the operation that drag bucket forklifts are arranged on the stope and the waste dump is not required any longer, the requirement for the number of the drag bucket forklifts can be reduced, the operating radius of the drag bucket forklift is increased, the operating capacity of the drag bucket forklift is improved, the purchase cost is reduced, the exploitation quantity is increased, and the exploitation rate is improved.

Description

technical field [0001] The invention relates to the technical field of open-pit coal mines, in particular to a dragline operation method. Background technique [0002] The dragline shoveling process plays an extremely important role in foreign open-pit coal mines. At present, the output of open-pit coal mines using the dragline shoveling process accounts for about 30% to 60% of the world's total coal output. Restricted by various factors such as national economy, equipment manufacturing capacity, mining concept, management level, etc., the application of drag bucket shoveling and stacking technology is relatively late in my country. The drag-bucket dumping process requires that the coal seam should be close to the level or gently inclined, the coal seam structure should be simple, the quantity should not be too much, the coal field is rich in reserves, and there is enough area to arrange the working line to make full use of the equipment capacity. From the perspective of pro...

[0003] Although the dragline has many advantages, its working capacity also has a certain limit.

When the operating capacity of a single dragline cannot meet the production demand, or the working radius of a single dragline cannot meet the needs of on-site operations, the current practice is to use double-shovel combined stacking operations. The biggest feature of this operation method is the use of There are two relatively independent dragline standing platforms at the bottom of the dump. Since the dragline standing platforms built on the side of the dump are basically located inside the dump, a larger discharge can still be obtained under the conditions of large coal seam thickness or multiple coal seam mining conditions. Field space

However, due to the high purchase cost of a single dragline, the production cost is too high, so it is necessary to design a dragline operation method to meet the production requirements in the case of a single dragline
