In order to continuously improve the mining efficiency of mines，Accelerate the construction of smart mines，Further assist the company’s high-quality development，Recent，Sunjiacha Longhua Mining Company actively conducts research，Convened multiple special meetings to demonstrate the purchase of fast anchor digging machine，The final decision was based on the introduction of the first rapid anchor digging machine，Introduction of the second set of rapid anchor digging machine。

Early July，After the MB670-1 M88 gamebolt digger is transported to the air shaft，The first comprehensive mechanized excavation team immediately organized technical personnel to debug and make technical modifications to the equipment before entering the well。Period，Through repeated communication between technicians and manufacturers and on-site tracking and debugging，Successively inspect the dust removal devices、Cutting device、More than 10 safety upgrades and technical transformations have been carried out on 7 systems including the left and right bolters，Further improved the applicability of equipment。The afternoon of July 15th，MB670-1 type anchor digging machine entered the well smoothly。

This integrated anchor digging machine is equipped with a fully automatic cutting cycle function，The cutting head of the equipment can be moved to a predetermined coordinate axis within a predetermined time window。The same cutting process is repeated over and over again，Make excavation operations more efficient。Can complete anchoring at the same time、Anchor rope、Permanent support for anchors，The tracks cause little damage to the bottom plate，High M88 appsafety factor。During excavation work，No need to adjust the machine frequently，Effectively reducing the number of laborers。and，The subsystem is equipped with a new wet dust removal fan，Greatly reduces on-site noise。These features not only improve production efficiency，Also reduces production costs。

In addition，The electronic hydraulic system of the MB670-1 bolt digger has also been upgraded，Including new simplified hose、Contact layout and new more compact power pack，And new switchboard、Monitor and remote control system。This time the company’s second set of integrated anchor digging machine is installed into the well，Not only can it greatly improve the excavation efficiency、Operation intelligence level，It also marks that the overall intelligent mine construction of Sunjiacha Longhua Mining Company has entered a new journey。(Author: Wang Yao Feng Meng  Editor: Wang Yu)
