Characteristics of Brazilian Splitting Failure and Acoustic Emission Evolution of High-temperature Coal After Liquid Nitrogen Cooling Treatment

Characteristics of Brazilian Splitting Failure and Acoustic Emission Evolution of High-temperature Coal After Liquid Nitrogen Cooling Treatment

The use of fracturing technology to enhance the permeability of coalbed methane reservoirs is an essential approach to strengthen coalbed methane development. For deep and high-temperature coalbed methane reservoirs, liquid nitrogen fracturing technology injects low-temperature liquid nitrogen into...
