Purpose. To present technical and economic substantiation of self-propelled machinery application expediency in mines of Krivorozhsky bassin through the introduction of new technologies for stoped excavation opening and room cutting.

Methodology. For the technical and economic substantiation of self-propelled machinery application expediency in underground mines in the basin the following general scientific and special methods of investigation have been used: a method of critical analysis and synthesis of theoretical studies, laboratory studies, a method of systematic approach, a method of economic and mathematical modeling. The software Excel 7.0 for OS Windows XP Professional was used for controlling of timeliness and accuracy of the calculations.

Findings. The problem of introduction of self-propelled drilling, and loading and haul equipment in the mines of Krivoy Rog basin should be solved in complex. For this purpose it is necessary and economically reasonable to apply the new technologies for development mining, preparation of horizons and block cutting.

Originality. New correlations between costs and geological and technological conditions of iron ore mining by underground methods were set. And performance correlations when comparing the proposed and existing technologies of broken ore transportation in underground conditions.

Practical value. The flow sheet of complex reconstruction of the mines of Krivoy Rog basin has been developed. For opening the ore fields in the deep horizons we propose to apply the scheme of opening horizons of concentration resulting almost 2-fold decrease of costs spent on mine capital work and the time commissioning work horizons.
We offer the technology of preparing the horizon and first workings able to reduce the amount of preparing operations by 50%.
We offer technologies resulting 1.5–2.5 times increase of the intensity of drilling and transportation of broken ore from rooms.
The proposed measures can reduce the cost of mining in the mine in whole, and allow efficient use of expensive self-propelled machinery in mines of Krivoy Rog basin.
