Stackable tower lifts, selection of equipment for horizontal transportation of rock mass

Authors: Tochilin V. I.

The article is devoted to the analysis of the proposed ways to reduce the volume of opening in the development of poor-commodity and low-volume diamond ore deposits with the introduction of the principles of non-use of the quarry board as a structural element for the placement of transport communications, including the use of armorless structures of non-working boards. The possibility of using cable cranes and built-up tower lifts (NBP) for geotechnology data is shown. In particular, the possibility of using NBP in the refinement of sub-quarry stocks and the installation of several NBPs on the periodically lowered sole of the quarry is shown. At the same time, it is possible to equip part of the NBP with skip lifting units. It is proposed to consider the issue of creating a boom harvester with a hammer rotor. The possibility of using cable cranes is analyzed, taking into account new developments and the introduction of remotely controlled, robotic equipment and, on their basis, unmanned technologies for working in the quarry industry. The possibility of using NBP without drilling and blasting operations in combination with a new inertial-shock method of layer-by-layer destruction of rocks is considered. Calculations of the capacity of the transport bridge for variants of horizontal cyclic movement of the rock mass using a self-propelled trolley and a belt conveyor were carried out. The possibility of providing an annual capacity of a transport bridge of up to 1.1 million is shown. m3/year and the possibility of using a belt conveyor for selective delivery of rock mass at the specified capacity. The expediency of using kinetic energy storage devices in power supply schemes is shown, which will significantly reduce peak loads in the power grid and increase the energy efficiency of the NBP lifting unit and the mechanism for moving a self-propelled trolley.

Keywords: beanless non-working board, refinement of quarry stocks, cable cranes and stackable tower lifts, movement of rock mass.
