Abstract：As fully mechanized working face crossing fault is of great difficulty,low security,and hard disaster prevention,etc.,take 4236 fully mechanized working face crossing F1 oblique fault in Huashan Coal Mine as an example,this paper introduces the technologies including abnormal area determination by fixed point method,water disaster avoidance by drilling detection,gas control with densified gas drainage,surrounding rock reinforcement with advance grouting,and the special supporting and protection technologies during fault crossing against falling coal,skidding,flying rock,gangue fleeing,as well as the end support moving and roof control technology.The result showed that,4236 fully mechanized mining face successfully crossed the fault,the recovery rate of high-quality resources was improved,obtaining favorable economic benefits and rich experience in production safety.
