ON THE METHODOLOGY OF EXPLORATION AND GEOLOGICAL-ECONOMIC EVALUATION OF ROAD STONE DEPOSITS IN THE EASTERN PART OF THE HOLY CROSS MTS.Abstract. The areas particularly interesting in terms of the amount of reserves and geological and mining conditions include the eastern part of the Kielce-Łagów Synclinorium and the Klimontów Anticlinorium. Altogether 14 deposits with reserves reaching 636 million MG have been recorded. Six of them are currently quarried. Effective development of this area requires some improvements as far as exploration method and reporting of exploration are concerned. Selected unconventional exploration methods have been implemented, particularly geophysical surveys, supplemented by surface mapping, routine geological observations in active mines and permanent quality control of the raw material. The paper presents a new proposal of point evaluation of geological-mining conditions of road stone exploration. A total of 16 factors were taken into account, including 6 geological, 6 mining and 4 environmental ones. The deposits have been categorized into three groups: (1) attractive deposits, (2) deposits of moderate mining difficulties and (3) non-attractive deposits (hardly possible for use). According to the evaluation, the deposits from this region fall into two categories: easy to be exploited or slightly difficult to be exploited.
