Underground coal mine movable type integrated automatic grouting system and use method

Abstract

The invention provides an underground coal mine movable type integrated automatic grouting system and a use method. The automatic grouting system comprises a powder conveying device, a grout making device, a grout storing device, a grouting device, a moving mechanism and a control device. The powder conveying device is used for conveying powder to the automatic grouting system, the grout making device is used for making the powder conveyed by the powder conveying device into grout, the grout storing device is used for storing the grout made by the grout making device, the grouting device is used for conveying the grout in the grout storing device, the moving mechanism is mounted on the bottom of the automatic grouting system, and can wholly move the grouting system, the control device is used for controlling the automatic grouting system to be started and stopped, when the powder enters a grout making bucket, dust removal is carried out, work environment is improved, for the position needing grouting, the system only needs to be wholly moved to the grouting point, labor intensity of a worker is reduced, device repeated dismounting and mounting can be avoided, the service life of the grouting system is prolonged, and the production cost is indirectly saved.

Description

technical field [0001] The invention belongs to the technical field of coal mine production equipment, and in particular relates to a movable integrated automatic grouting system in a coal mine and a use method thereof. Background technique [0002] Due to the needs of coal mine grouting reinforcement, water blocking, gob-side retaining, fire prevention, and gob filling, it is often necessary to build a grouting or filling station to put cement, fly ash, high water or super high Powder materials such as water materials are made into slurry, and then pumped to complete the grouting or filling project. The existing grouting or filling stations mainly have the following problems: [0003] (1) The degree of automation is low, the labor intensity of workers is high, and the work efficiency is low. The powder is mainly loaded into the well with standard bags, and then the pulping work is completed by manual feeding. The labor intensity of the workers is extremely high, and the p...

Problems solved by technology

[0003] (1) The degree of automation is low, the labor intensity of workers is high, and the work efficiency is low

The powder is mainly loaded into the well with standard bags, and then the pulping work is completed by manual feeding. The labor intensity of the workers is extremely high, and the pulping efficiency is limited by the feeding speed, which is difficult to improve; although some mines have excavated large-section chambers and built temporary storage underground silo, but it still needs manual feeding and loading, and only semi-automatic pulping can be realized

[0004] (2) 25kg or 50kg bagged materials are mainly used, and it is difficult to use ton bags or bulk materials. Since the pulping system mainly adopts manual feeding, there is no effective unloading equipment underground, and powder materials are mainly transported in bags and stacked manually. When in use, it is transported to the place of use by carrying it on the shoulders, which is extremely labor-intensive

[0005] (3) The flexibility of the grouting station is poor

The underground grouting point often needs to be changed. The grouting station must be flexible and easy to move. Most coal mining companies now use bucket mixing, and the materials are mainly stacked. They need to be excavated for storage, which lacks flexibility.
