Embodiment 1

[0025] like figure 1 As shown in the figure, prepare the water for preparation, and quantitatively introduce the water into the two slurry mixing tanks according to the demand through the water pump, flow meter and three-way valve, and pass the two kinds of quick-setting mud base materials A and B through the quantitative feeding device. According to the required amount, it is quantitatively introduced into two pulping mixing tanks, and the two basic materials A and B are mixed with water through mechanical stirring to prepare two kinds of slurries with a material-to-water mass ratio of 1:(1-3).

[0026] Two sets of mud plunger pumps of the pumping system are used to pump out the A slurry and the B slurry in the slurry mixing tank for transportation. The volume ratio of the two is 1:1. It is fully mixed in the mixer to form a quick-setting blasting mud slurry for filling the blasting holes. The mixed rapid-setting blasting mud slurry enters the filling pipeline, and is transpo...

Embodiment 2

[0028] like figure 2 As shown in the figure, prepare the water for preparation, and quantitatively introduce the water into the two slurry mixing tanks according to the demand through the water pump, flow meter and three-way valve, and pass the two kinds of quick-setting mud base materials A and B through the quantitative feeding device. According to the required amount, it is quantitatively introduced into two pulping mixing tanks, and the two basic materials A and B are mixed with water through mechanical stirring to prepare two kinds of slurries with a material-to-water mass ratio of 1:(1-3). The A slurry and the B slurry are transferred to two slurry storage tanks by means of pump or self-flow and transported to the construction site for use.

[0029] When the blast hole needs to be filled, the slurry A and B in the slurry tank are pumped out respectively by the slurry plunger pumps of two pumping systems for transportation. The volume ratio of the two transportation is 1...

Embodiment 3

[0031] like image 3 As shown in the figure, prepare the water for preparation, and quantitatively introduce the water into the two slurry mixing tanks according to the demand through the water pump, flow meter and three-way valve, and pass the two kinds of quick-setting mud base materials A and B through the quantitative feeding device. According to the required amount, it is quantitatively introduced into two pulping mixing tanks, and the two basic materials A and B are mixed with water through mechanical stirring to prepare two kinds of slurries with a material-to-water mass ratio of 1:(1-3).

[0032] Using the mud plunger pump in pumping system 1, the A slurry and the B slurry in the slurry mixing tank are pumped out and transported respectively. The volume ratio of the two is 1:1. Mixed to form a quick-setting gun mud slurry for filling the gun holes, the mixed quick-setting gun mud slurry is fed into the plugging pipeline, and the mud pump in the pumping system 2 is used...

Abstract

The invention discloses a blasting hole mechanical filling construction process method using quick-setting stemming, and relates to the technical field of engineering blasting. The method comprises the following steps: in a construction process, a quick-setting stemming material is used as a blasting hole filling material, the quick-setting stemming material and water are prepared into quick-setting stemming slurry with the mass ratio of the material to the water being 1: (1-3), the quick-setting stemming slurry is conveyed into a blast hole through a pipeline in a pumping manner, and the quick-setting stemming slurry is quickly set into solid stemming, so that a good blocking effect is achieved. The quick-setting stemming material is composed of a basic material A and a basic material B, the device is applied to a blasting operation construction scene, has the same filling effect and effect as manual stemming filling, can be pumped to achieve blasting operation blast hole filling mechanical operation, and is beneficial to improving the automatic operation level and the blasting effect of blasting operation.

Description

technical field [0001] The invention relates to the technical field of engineering blasting, in particular to a construction technique for mechanized filling of blasting holes using quick-setting mud. Background technique [0002] The filling materials used in blasting construction to block blast holes are commonly known as blast mud. At present, the most commonly used blast mud materials in underground blasting operations are clay soil and loess, which are obtained locally. Proportion fine sand. Although there are research reports on new packing materials such as expansive cement and polyurethane materials, they have not been practically applied in engineering. [0003] At present, all the blasthole filling operations in the underground blasting project need to be carried out manually. The mud machine only makes the loose mud into a column, and when filling, it still needs to be manually fed into the gun hole section by section and tamped with a cannon stick. The process...
