Abstract:Purpose of the research was to improve efficiency of underground gas drainage from the rock-coal massif. It is substantiated that most promising solution of the problem of increasing efficiency of gas drainage from the massif is to mine additional gas-drainage road. This approach allows separating processes of coal mining and methane recovery in space and time. The Ukrainian normative documents is recommended to mine the road behind zones with high rock pressure. We found that in difficult conditions of coal s… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
