Abstract: In order to ensure the safety and speed of 15209 fully mechanized face passing through F4 normal fault，improve the coal pillar recovery，reduce the rock breaking amount and reduce the failure rate of mechanical equipment in the face，youxianshan coal mine，through technical research，reasonably analyzes and compares the construction scheme of working face passing through F4 fault，puts forward the construction scheme of loosening blasting and pitching method，and puts forward the construction scheme of pitching roof during the pitching recovery of working face The combined support measures of "Wedge impact advance support + grouting + Construction constant resistance anchor cable hanging shed" can improve the raw coal recovery by 42 000 t compared with the traditional construction scheme through practical application.At the same time，the combined support measures of roof can control the subsidence and fragmentation of the inclined roof，solve the technical problem of difficult top coal reservation during the period of the inclined roof，and ensure the work Face safe and efficient mining.

Key words: Fully mechanized working face,Fault mining scheme,Inclining method,Roof support,Application analysis
