“…Consequently the coal losses do not exceed reasonable limits. This scheme allows simultaneous use of two backhoes, every of which works in its own isolated sector -one for rock and another for coal [22]. We conclude that the implementation on this scheme will eliminate coal losses caused by un-excavation of coal seam.…”

-Hydraulic backhoes are widely used in Kuzbass (Western Siberia, Russia) because the level of coal loss during their operation is much lower compared with traditional quarry excavators -shovels. However, one of the mining enterprises' designing problems is insufficient consideration of technological possibilities of this type of equipment, which leads to additional losses of coal and economic effect reduce. This article presents an approach to adaptation of the slope height considering the capabilities of backhoes in seam extracting which can sufficiently decrease coal losses and intensify open pit mining. This approach is based on a system of mining and geometrical calculations, allowing carrying out an accurate selection of equipment and technology to adapt the use of hydraulic backhoes to minimize coal losses.

“…As a result, technical solutions with bracket assemblies' attachment points of a disk tool to polygonal prisms of arrow-type working bodies of tunnelling machines were proposed and developed [1][2][3]. The basic design of two-crown arrow-type working body with a disc tool on trigonal prisms according to the Russian Federation patent № 2455486 can be recommended for installation for national and foreign tunnelling machines of selective action.…”

“…It is necessary to note the special role of the attachment point of a disk tool for a working body of a mining combine, since the efficiency of the destruction of the rock mass, the reliability of the fastening of a disk tool and the stress-strain state of the entire construction depends on its design parameters [1][2][3].…”

An important task in the technological process of a mining enterprise is preparatory mine working performance, as effective operation of an entire mining complex depends on rate and quality of drilling. Therefore, the main factor affecting the performance of the process of underground mining is the correspondence of design and operating parameters of the working bodies of tunnelling machines to mining and geological conditions. The underground mining operations showed that rocks with a strength f ≤ 10 and high abrasiveness are to be destroyed with disc tools, providing higher strength, wear-resistant parameter and low dust formation in comparison with cutters. The usage of disk tools on the working bodies of tunnelling machines of selective action is a poorly studied task and requires special research of the questions of destruction, crushing and loading of rocks at reverse working modes. It has been established that researches aimed at design development of an attachment point of a disk tool for arrow-type working bodies of a tunnelling machines is an urgent scientific task. The original technical solutions for the design of the attachment points of disc and cutter tools are proposed to improve the processes of cutting of working bodies in the face massif, dust suppression, sealing and mounting-dismounting operations at the operation of shearers and tunnelling machines.

“…The concept of "nature and society" system should be transformed into the "nature-society" system. The scientific and technological revolution and the rising degree of mechanization [12][13][14][15][16][17] reveals human's complete dependence on the animated and inanimate nature resources. This especially influence on the environment during mineral resources extraction [18][19][20][21][22][23].…”

Abstract.The most important issue of scientific and technological progress is considering the environment challenges of industrial development. It means that the progress must be ecologically oriented and environmentally friendly. The most adequate concept for the approach to the issue of "man -society -nature" relations is the ontology of the noosphere -the idea of a common space for human beings and nature. It presents an ideal example of an optimistic attitude towards the coordination between accelerating the scientific and technological development and natural resource saving. However, to maintain the balance between human needs and environmental processes determined by this concept, it is essential to include the lean production training into technological development of society.
