Abstract

The invention discloses a stone excavation method based on a mine hammer. The method comprises the following steps of enabling construction equipment to enter a site, wherein the construction equipment is moved to the construction site where stone is to be excavated; selecting a hammering working face, wherein the construction hammering working face is selected on the stone to be excavated, a fallface is arranged on one side of the hammering working face, the height of the fall face ranges from 1 m to 5 m, and the distance between the hammering working face and the fall face ranges from 0.5 mto 3 m; performing punching, wherein the mine hammer is used for hammering a plurality of operation holes in the hammering working face; and performing stone decomposing, wherein the stone which is held open from the hammering working face is dug out and secondarily crushed through a crushing hammer and/or a rock arm, and the stone is crushed into dimension stone which is easy to load and transport; and performing truck loading and transportation. According to the method, stone excavation is conducted through the mine hammer in a non-blasting mode, explosion damage is avoided, combined line production is adopted through the mine hammer and other devices, the method can adapt to various terrains, the construction speed is high, and the construction efficiency is high.

Description

technical field [0001] The invention relates to the field of earthwork excavation construction, in particular to a method for excavating stonework based on a mine hammer. Background technique [0002] At present, when excavating stonework at home and abroad, the method usually adopted is mainly the drill and blast method. The drilling and blasting method is a method of excavating rocks by drilling, charging, and blasting. This method has developed from the early days of manual drilling and hammering to drill holes, and detonating individual charge packs one by one with fire detonators. Drilling by trolley or multi-arm drilling rig, blasting technologies such as millisecond blasting, pre-splitting blasting and smooth blasting are applied. During the construction process of the drilling and blasting method, vibration, impact, noise, dust flying debris, toxic gas and other harmful wastes will be generated, which will have a great impact on the surrounding environment; in addit...
