limestone mine Study on Mining Technology and Equipment Configuration of Limestone Mine The research on the mining technology and production equipment for a limestone mineral resources set principles，selection of large-scale modern mining machinery installed wilderness drilling technology，relying on the series parallel type double row line network model hole with fine blasting
rock drill rig Development of Hydraulic Rock Drills and Hydraulic Drill Rigs During the exploitations at metal mines and the open-pit rock-drilling jobs, the drilling and blasting method is the only effective rock-breaking method. Hydraulic rock drills and hydraulic rock drill rigs are cost-effective rock-breaking equipments. The computer-control automatic
drilling jumbo Increasement of advance per attack of roadway drivage by extending the drilling pipe length for drilling jumbo In Chambishi Copper Mine in Zambia, large scale trackless equipments are used and the section size of roadway and stope is large. In order to exert the advantage of high efficiency of the large scale trackless equipments, increasement of advance per attack of roadway drivage is required.
drilling jumbo Application of Boomer 281 Drilling Jumbo in Zijinshan Gold-Copper Mine Due to the disadvantages of relative backwardness of original mining equipments，high labor intensity of workers，poor quality of air around，low tunneling efficiency and low safety in a mine，the efficient and intelligent trackless mining equipments such as the new type hydraulic drilling jumbo and
drift excavation Borehole-locating technique with drill jumbo and its application In conventional drift excavation，midline and waistline are demarcated manually which is a complex process and prone to errors．At the same time，in the drilling process，the actual location of boreholes often deviates from the designed location，which will result in uneven excavation face
rock drilling jumbo Conversion of Top Plate on Propulsion Beam of a Kind of Three-boom Rock-drilling Jumbo In order to improve the control precision of overbreak and underbreak of tunnel when using rock-drilling jumbo，the top plate structure on propulsion beam of a kind of three-boom rock drilling jumbo is analyzed． The fault，overlarge distance between guide hole of drilling pipe of top plate
Full hydraulic jumbo Application of full hydraulic drilling jumbo in the excavation of hard rock roadway in copper mine With the rapid growth of economy, the growing demand for metal mineral resources. In metal after the mining of mineral resources to roadway advance deposit has been the key of the mining operation. In roadway homework to use appropriate drilling harvesters,
