Softening of a Dirt Bed within a Coal Bed in Conditions of “Romanovskaya” Mine Using an Interval Hydraulic Fracturing (IHF) Method

Abstract
It shows the results of the mine-based tests aimed at the softening of a dirt bed within the “Abramovsky” coal bed of (“Romanovskaya” mine) using an interval hydraulic fracturing (IHF) method based on the changes in physical and mechanical properties of the said dirt bed obtained by through laboratory testing. Based on the performed work the conclusions were made as to the efficiency of the said method for decreasing a dirt bed strength and consequently improving coal production when developing similar beds.

Keywords
Dirt bed, Interval hydraulic fracturing, Sealer, Valve, Water saturability, Saturation rate.

Mine Methane Problem in Russia

Abstract
Anatoliy D. Ruban made his report on the subject of “Mine Methane Problem in Russia” at the fifth conference “Coalltrans Russia and CIS 2011” held in Moscow on June 27 to 28 2011. The summary of the conference was published in No 9 of “Ugol” magazine. Given the topicality of the mine methane problem solution in Russia’s coal industry we would like to offer our readers a complete version of this report. For Russia’s coal industry that develops the world’s biggest methane-containing coal beds with the average methane content of 8.3 kg/ton of coal against the world’s average of 4.9 kg/ton the elimination of a negative influence of the “gas factor” is an extremely burning issue.

Keywords
Mine methane gas, Methane-rich mines, Injury rate, Degassing, Regulatory and Methodological documents, Automated control system, Mine methane utilization.

Energy and Chemical Laws for Methane-Air Explosion Formations in Dusted Atmosphere of Coal Mines

Abstract
It shows that the issue of explosions within mines involving methane and powdered coal dust can be resolved on the basis of taking into account the fundamental chemical processes that occur when gas-dust-air mixture is heated. The methods must interrupt chemical reactions of explosive reactions forming a detonating mixture, water and acetylene vapors with high energy emissions. It specifies the laws of formation of these reaction products at different methane concentrations. It suggests for the first time that the number of free radical moles on the dust particle surface be taken into account when evaluating the energy emitted in the thermal decomposition of powdered coal. The results are the basis for choosing practical methods of preventing explosions and fires that involve methane and powdered coal.

Keywords
Methane and powdered coal explosion prevention; methane concentrations; energy emissions in reaction product formation; chemical laws; chemical reaction interruption; microscopic dust; free radicals; detonating mixtures; acetylene.
