摘　　要：针对振兴二矿综采工作面粉尘浓度高,煤体松散易片帮等问题,通过现场实施煤层注水技术,观察该技术对这两个问题的改善效果。结果表明:工作面粉尘浓度大幅度降低,降尘率达到68. 7%;工作面超前支承压力峰值卸压达到34. 2%,煤壁片帮现象得到较好的改善。煤层注水措施对促进该矿安全生产和保障工人身体健康方面具有积极意义。To the following problems of high dust concentration of fully mechanized working face and loose coal and rib spalling, according water injecting in field and observing improve effect. The results showed that dust concentration of working face decreased significantly, the dust fall ratio arrived about 68. 7%, the peak value of the advance abutment pressure released about 34. 2%, and also rib spalling was improved better. Water injecting plays positive meaning to safety production and worker’ s health.
