The growing requirements and needs of users as well as a strong emphasis on pro-ecological solutions cause an increasing interest in battery-powered electric mining machines. Internal combustion machines consume oxygen, generate noise, fumes and heat, which affects work in underground mines, and minimizing these factors is expensive. Battery solutions allow achieving the same operational parameters...
Mechanical mining is a widely used method for separating material from mined rock in the mining branch, tunnelling, road and construction industries. Depending on the mechanical properties of rocks, most often defined by uniaxial compressive strength, various machines and tools are applied. Apart from rock strength, the efficiency of the mining process is determined by abrasiveness, which affects...
The changing requirements and needs of users as well as the demand for new mining machinery solutions pose a challenge for designers. Time spent on the design phase of a new machine is often reduced to a minimum. Small lot production and sometimes single piece production entails the necessity to frequently design and manufacture commercial copies, which are also prototypes. The only effective solution...
In underground mines, where the deposit is located at considerable depths, mining shafts are key excavations. The project of making the deposit available requires selection of appropriate shaft sinking technology adapted to geological and hydrological conditions and natural hazards. Shafts can be made using the classic drilling and blasting technique or mechanical cutting of the shaft face. Mechanical...
