The patented technology of VP series stripping head combines the crowbar action of pick and vibration frequency of hydraulic crusher, which successfully applies soft rock to underground mining.
Sandvik tc790 is our shuttle car for underground coal and soft rock mining, which can be operated behind various continuous mining machines. The electric machine is equipped with variable frequency drive AC, which can provide variable speed.
Underground soft rock mining is a group of underground mining technologies used to extract kerosene shale potash and other minerals or geological materials from sedimentary rocks, because the deposits in sedimentary rocks are usually layered and relatively less hard. The mining methods used are different from those used for mining deposits in igneous rocks or underground mining in metamorphic rocks.
The tripartite Committee on mining compared the plans for 700130 underground soft rock mining machine and 770010 underground hard rock mining machine, and found that some corresponding modules were equivalent modules. Employers should contact the local apprentice office for details of the requirements related to these equivalencies.

The general core for underground soft rock miners now consists of four modules, u5510, following ground and underground induction procedure u5511, general inspection u3126 scale loose rock u5513 fully locking and marking prime mover and other related equipment 6 are there any module changes.
The 770010 underground hard rock miner's public core - underground hard rock miner program contains a two-day theory, including information from occupational health and safety laws, as it is a public core module, and an in-depth practical course over the remaining 18 working days of the project for a total of 4 weeks.
Ramjacks, a solution for underground soft rock mining, cooperates with original technology manufacturers to focus on soft rock mining, ensuring that both fire and non fire mines can use advanced technologies for underground production and safety management.
Underground mining of soft rock refers to a group of underground mining technologies, which are used to extract kerosene shale, potassium salt and other minerals or geological materials from sedimentary rocks. Because the deposits in sedimentary rocks are usually layered and relatively less hard, the mining method adopted is different from that of deposits in mining. Igneous rocks or metamorphic rocks can be seen underground.
