Study on directional hydraulic fracturing of prefabricated fissures in top coal
In order to improve the cavity and working surface operating environment of thick hard top coal, the top coal prefabricated fissure hydraulic fracturing technology was proposed.The basic principle of directional fracturing was studied and the stress models of borehole and fissures were analyzed then...
