Geodynamic methods for assessing methane distribution in bituminous coal deposits and measures to intensify methane fluxes during mine gas drainage

Article preview

This paper explores states of methane within the coal bearing stratum and shows heavy dependency of the intrastratal gas migration on the forms of porous space and petrographic properties of coal. The adsorbed methane is found to be predominant in the coal of Kuznetsk Basin. Different forms of coal diffusion and filtration are described revealing their dependency on geological and thermodynamic conditions. The paper provides justification for the primary focus on geodynamic processes when designing gas drainage systems and applicability of morphometric methods and remote sensing data for their identification. The significance of researches into the processes activating exothermic reactions resulting in methane transition to free state is explained. The paper presents the results of using seismic-acoustic stimulation techniques as one of the practical approaches to addressing this issue. Results of successful industrial testing have been compared with the results of numerical modelling of stress-strain state, which can also be managed through seismic-acoustic stimulation.

The technology of extracting gaseous fuel based on comprehensive in situ gasification and coalbed degassing

Article preview

The study considers a comprehensive technology (designed and patented by the authors) of developing coal and methane deposits which combines in situ gasification of lower coalbeds in the suite of rock bump hazardous gassy beds, extraction of coal methane and mechanized mining of coal. The first stage of the technology consists in mining gaseous fuel that enables one to extract up to 15-20 % of total energy from the suite of coalbeds. Geodynamic zoning is used to select positions for boring wells. Using the suggested technology makes it possible to solve a number of tasks simultaneously. First of all that is extracting gaseous fuel from the suite of coalbeds without running any mining works while retaining principal coalbeds in the suite and preparing them for future processing (unloading and degassing). During the first phase the methane-coal deposit works as a gas deposit only, the gas having two sources – extracted methane (which includes its locked forms, absorbed and adsorbed) and the products of partial incineration of thin coalbeds, riders and seams from thee suite. The second stage consists in deep degassing and unloading of coal beds which sharply reduces the hazards of methane explosion and rock bumps, thus increasing the productivity of mechanized coal mining. During the second stage coal is mined in long poles with the account of degassing and unloading of coal beds, plus the data on gas dynamic structure of coal rock massif.

Ways for providng safety in designing of intensive coal mining at the Kuznetsk basin

Article preview

Problems are generalized for the purpose of providing safety in coal deposits mining at the Kuzbass. It was shown that the basis for providing safety should be a complex of safety measures in corporating a repeat geodynamic zooming of the overall Kuzbass, individual deposits and mine fields, multiphase degassing at all stages of mining , and also the gaseous, seismic, hydrogeomechanical and electromagnetic monitoring at productive mines. It was suggested to work out safety regulations for providing safety during intensive coal mining not for each individual holding, but for the whole Kuzbass.

Interaction between seismic activity in Kuzbass and open-pit operations

Article preview

The analysis of graphs shows seismic events repeatability and seismic events distribution during the day, by days of the week and by months was made. It is shown, that seismic activity in Kuzbass region has a mixed natural and manmade character and figures of repeatability have interim character, the majority of seismic events occur in the time of blasting operations in open   pit mining, but the distribution by month of the year corresponds to planetary pattern – the larg est number of events takes place in March, August and December. It  was suggested that the  spring increase in  seismic activity lead to reduced  stability of mine slopes during the snowmelt  of landslides formation.

Phenomenon of dilatancy in fragmented rocks

Article preview

The design procedure of dilatancy changes of volume of the fragmented rocks is offered. By means of this technique the mechanism of loosening in rock blasting is considered. The behaviour of fragmented rocks at compression and vibration is studied. Quality estimations of the processes occurring in zones of destruction in rock massif at shift are made.
