The establishment of the characteristics to mechanical cutting of the rocks through chipping, just as it happens in practice for the bucket-wheel excavator having teeth, represents an elemental problem and underlies the concrete knowledge of rocks dislocation. Interdependency laws among the geometric parameters and technological ones of the chipping teeth, the parameters of the dislocated chippings and the parameters of the cutting regimes which can be established taking into account qualitative and quantitative a...

This paper presents a technical solution proposed for the mining drilling equipment command system, used for digging the horizontal mining works. The manufacturing industry of mining machinery in Romania and from different countries achieved a wide range of equipment for digging the horizontal mining works. As a result of the activity undertaken by a research team from the University of Petrosani, the drilling equipmentпїЅs with one manipulator arm (IMP-1) and two manipulator arms (IMP-2) were designed and constru...
