The machinery predominantly used for overburden removal as well as for lignite and inter-bedded waste layers extraction in surface mining operations in Europe, is the bucket wheel excavator. The existence of hard rock structures-layer or boulder types-with higher cutting resistance as the normal rock-produces downtimes, increased equipment wear, or even severe damage of the bucket wheel excavator's structures or operation parts, resulting in increased energy consumption, lower production rate and finally increased mining costs. The present paper, based on some aims and results obtained in BEWEXMIN RFCS project is devoted to the development of solutions to reduce failure rates of bucket wheel excavators working in these conditions. This outcome can be achieved by developing methods for adaptation of already working excavators to those conditions and prescription of standard requirements for newly built ones, and on the other hand, a system of continuous surveillance of machinery superstructure's stresses and in due time signaling the emerging threats.
