Abstract. Brief information about Donets Basin and one of its districts is presented. Location of the Pokrovskaya Mine field in the basin and of area under this study is shown. The article briefly describes geological and tectonic characteristics of the deposit. Three levels of tectonic displace-ment in the mine field are given. Fault type low-amplitude displacements, which are specific for this mine conditions, are considered in details. Displacement parameters and their impact on the di-lution and losses during the coal mining are considered. Preliminary calculations show that about 30 % of the mine field is occupied by the fault zones. The low-amplitude displacements impair the coal mining geological conditions and cause gas outbursts, dynamic and gas-dynamic phenomena, and spontaneous firings. Today, no reliable forecasting technique is available for such kind of dis-placements. Objective of further work will be development of methods for the low-amplitude tec-tonics forecast.

Keywords: mine fields, low-amplitude displacement, forecasting techniques
