Preliminary analysis on stress state in front of and after fracturing of coal seam and sandstone
The maps of stress measurements for two physically different target seams in front and after fracturing are presented.The maps show differences of extending ways and influence scopes of artificial fractures in two different seams.This method provides some useful geological information for well design in coalbed methane (oil,gas) development.
