A complete characterization of cleat distributions and orientation may provide a better tool for indirectly estimating porosity and permeability in coal reservoirs as critical parameters for coalbed methane extraction. This paper is presented results of detail study cleats development within Miocene coal seams as part of CBM exploration and development. Most data were collected on mine walls (cross-section view measurement). Cleats data were collected for several coal seams from 60 scan lines and 39 windows measurement locations with total 20,000 cleats were measured from outcrops. Three major cleat orientations; WNW-ESE, NNW-SSE, and NE-SW. The relationship between cleat spacing and coal rank: bright coal (vitrain) generally have smaller cleat spacings than dull coal (durain). Coals with low ash content tend to have smaller cleat spacing than coals with high ash content. Relationship between coal density and calorific value shows high calorific value with low ash content tends to have large density. This suggests that coal composition related to cleats characteristics. This cleats origin might be subjected from several processes particularly superimposed by later processes such as hydrostatic pressure and tectonic stresses.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Ash contents,Coal composition,Coal density,Coal reservoirs,Exploration and development,High-calorific-value,Measurement locations,Tectonic stress[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.3997/2214-4609.20140608[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
