Design Procedure for Roof Bolting in Permafrost Coal Mine Underground Workings
Abstract
The paper presents a methodical reference for designing a double-level roof bolting of coal mine development workings performed in permafrost rocks. In order to provide resistivity of enclosing rock of the workings and to slowdown the rock melting and sheeting, the use of roof bolting in combination with frost-protection material is studied.

Improvement of Mining Machines
Abstract
The paper presents the results of the author]s research work concerning the creation of heading machines (combines, complexes and mountings) using his own developments on roof formation directly both in the mine fore-breast, by application of rock bolt erection technique, where the roof bolt — it is also an anchor with disposable chisel and with resin from pump plants instead of ampoules, and on the combine’s side. Superimposition of power-driven breaking with drilling and blasting operations when conducting mine workings by mixed face using a single combine aggregated complex without operator at site of drilling and rock bolt template erection is achieved, according to certification of conducting and anchoring of mine workings. Îñóùåñòâëåíî close-together timberman arrangement within the limits of heading machine dimensions, which enables mobility of complexes when conducting mine workings with twofold productivity improvement is implemented.

Metal-Coal Beds and New Technique of Their Integrated Development
Abstract
The characteristic feature of some Kuzbass and Far Eastern coal deposits is that the coal ash contains rear-earth metals (zirconium, germanium, yttrium, uranium compounds etc). Extraction of coal accompanying metals is performed either using surface wells - underground leaching, or by dissolution of rare metals from the ash dumps accumulated in immediate proximity of coal power plants. This paper examines the new technology of development metal and coal layers, consisting first in their underground gasification, and then in rare metals leaching out of the ash dump mass left in the exhaust underground gas generator after completion of coal gasification. Thus, new technology succeeds to minimize environmental consequences.

Geological Features of Mine Coal Bed Self-Ignition and Goaf Ventilation Flow
Gas Dynamics
Abstract
The analysis of present-day coal mine accidents, fires and causes of methane gas explosion is continuously performed with absolutely unprofessional approach to geology, this is the main reason that will always lead to a repetition of hazardous situations, with the subsequent decision to close or mothball hazardous coal mines. Based on the study of the real geological space it is proposed to analyze the up-to-date technique of fire seat suppression in the coal mines. The basic schemes of gas dynamics related to the massif mass are identified during coal bed self-ignition under conditions of the local mineralization of active chemical elements.

Mechanochemical and Sorbate Mechanisms of Coal Methane Formation and Emission
Abstract
The paper essentially justifies new representations about the coal methane nature. The methane content of coal layers is represented not as some volume of the methane accumulated in the porous structure of coal organic massl (COM) during metamorphism in the course of the geological history of the layer and retained in the coal by sorption strengths, butd as a result of mechanochemical destruction of COM with formation of the gas phase during change of stressed-deformed state of layer when conducting mining operations. It is shown that the natural coal methane content and sorption methan capacity have essentially distinguished physical and chemical essence.

Methane, Natural Methane Content of Coal Layers, Sorption Methan Retention Capacity of Coals, Mining Operations.
