Accordingly, determination of resource potential of coal bed

methane should be based on the separate estimation andgeological and economical evaluation of its extractive and theway of its production.In this view coal bed methane is classified into three types ofmineral resources that differ in their formation conditions and the

ways of their production and use:

Extractive coal mine methane, captured along with the miningactivities by means of vacuum-pump station of the system

attending the coal production degasification through thespecially drilled wells.

Extractive coal mine methane coal bed methane, extractedthrough the surface-drilled wells along with advance andattending degasification.

Methane of technogeneous deposits in the mined-out coal bedareas of the operating and closed mines, extracted through thesurface-drilled wells during the post-production degasification.

Methane of natural deposits in the untouched coal beds,

extracted by means of oil and gas complex technologies.7

As of the present moment the following documents were

approved and registered in the Ministry of Justice by theSCMR Order of 07 November 2008:

1)Regulations on application of the mineral resources andreserves Classification of the State Fund of mineral

resources in the geological and economical estimation ofgeneral (emissive) and extractive reserves in the areas ofattending technologically required degasification during

the coal deposits development, and2) Methodological guidelines on coal mine methane

reserves estimation in the areas of attendingtechnologically required degasification during the coal

deposits development.Therefore, regulatory and methodological basis was

prepared for estimation and state registration of the

extractive reserves of coal mine methane.

THE FOLLOWING DOCUMENTS ARE BEING

DEVELOPED IN SCMR:

1) Regulations on application of mineral resourcesand reserves Classification of the State Fund of

mineral resources in the evaluation of resources andestimation of the borehole methane reserves of thecoal deposits in the advance degasification areas bydaylight surface drilling;

2) Methodological guidelines on technogeneousmethane reserves and resources estimation in the

mined-out coal deposits;

3) Methodological guidelines on reserves andresources estimation of free methane deposits in the

untouched coal beds.10

Methodology of coal bed methane exploration mustcomply with the coal production safety requirementsand conform with methodology of extractive reservesexploration and estimation of oil and gas deposits.Specifically the criteria of coal deposit areas or

individual balance coal beds preparation to industrialdevelopment in the view of study of their methane-bearing quality in the stage of advance degasificationare to be determined. Based on these criteria, the

necessary density of boreholes and observation holesform the daylight surface is to be determined and,

accordingly, the coal reserves extracted duringadvance degasification are to be calculated.

In the stage of coal bed development the part of coalmethane emission reserves that should be extractedfrom the coal deposit by means of attendingdegasification is to be determined in order to providecoal production safety.

This concept of exploration and estimation ofthe extractive coal bed methane reserves isgoing to make the following actions possible:

estimation of this fuel and energy raw material,that can be actually extracted given thepresent technical and economical conditions:that is of extreme importance for planning andinvesting into methane production;coordination of coal production safety andecological problems dealing with coal mine

methane with the methodology of geologicalexploration in the methane and coal depositareas.
