The article has to grapple with the problem of creating an economically efficient and environmentally friendly technological process for a development of solid minerals in open-pit mining. In many mining countries of the world today, the depth of many open pits is already 400–600 m or more. At the same time, the cost of transporting 1 ton of rock mass when operating a quarry whose depth is 400 m is 65–70 % of the total cost of extracting 1 ton of minerals.
The object of research is technical devices for transport of rock masses in the technological process of development of solid useful deposits in open pit mining.
The main reasons are the need to construct transport routes for them by withdrawing the sections of the rock mass on above them, as well their lifting capacity is limited because of they all do use highly energy-intensive machines for transporting rock minerals. In article has been justified a skip cable winch supplied with a wheels moving along on a railroad way by using only a gravitational counterweight device for transporting rock mass from a place of their formation to Earth surface. There have been created a prototype of a planar skip winch with four cables for practical implement in open-pit mining. The theoretical and experimental investigations of the prototype have being confirmed its performance. The created skip winch will accomplish its performancing without using any energy machines even under adverse climate conditions. Its affected would allow to make an open-pit effectiveness to soar and environmentally do friendly because of there are all but excluded any transport vehicles whether on gasoline or diesel oil
