摘要
以3702大采高综采工作面回采为研究背景,对导致采面煤壁片帮发生原因进行分析,并针对性的提出片帮防治技术。现场应用后,采面煤壁片帮问题得以显著改善,片帮次数以及深度均大幅降低,虽然偶有片帮发生但是不会给采面正常回采带来威胁。
Taking the mining of 3702 fully mechanized mining face with large mining height as the research background,the causes of coal wall caving in the mining face are analyzed,and the prevention and control technology of caving is put forward.After field application,the problem of coal wall caving in the mining face can be significantly improved,and the times and depth of caving are greatly reduced.Although there are occasional caving,it will not pose a threat to the normal mining of the mining face.
