Abstract. The negative influence of mineral deposit development on environment and, mostly, on economical use of land resources in the quarries is analyzed. The article focuses on absence of necessary technologies for mining operations, which could increase volume of returned land resources that are subject to restoration. The technology is proposed for the ore layer mining, which simplifies execution of overburden and dump operations, decreases land resources usage, and is realized by means of extension of the entry trench, gradual advancing of temporary trench in the spoil bank and by backfilling and landscaping of previous trenches as the front of mining and dump operations advances. The parameters are specified for the technological scheme of deposit development, which help determining rational distance between the temporary trenches with taking into account costs of the ore extraction.

Keywords: open field development; inside ramp for vehicles; technological scheme; parameters for technological scheme; costs of the ore extraction.
