摘要
综放工作面由于后部放顶过程中产生的煤尘较大,致使工作面作业环境较差,煤层注水是工作面降尘的主要方法之一。根据泉店煤矿的煤层地质条件选取了合适的注水工艺及注水参数,不但起到了降尘的功效,而且取得了固结煤壁、防止片帮的良好效果。
The work of fully-mechanized top coal caving face generates much coal-dust which will worsen the working condition.Water injection to coal seam is one of the methods of dust reduction on working face.Take Quandian Mine for example,based on its geographical condition,the proper water injection technique and parameter were chosen,which not only decreased the coal-dust,but also consolidated the coal wall so as to avoid rib spalling.
