通过煤层注水润湿性能研究,优选出了适合煤层注水用的表面活性剂,针对唐口矿井煤层埋藏深温度高的特点和现场实际情况,全面研究了煤层注水工艺,确定了最佳工艺参数,并对实际注水防尘效果进行了测试和分析,取得了较好的润湿煤体和防尘效果。
According to the study of wetting property of coalbed water injection, a surfactant suitable for coalbed water injection is optimized. According to the characteristics of deep buried coal seam temperature in Tangkou coal mine and the actual site conditions, the waterflooding technology of coal seam is studied comprehensively and the optimum process parameters are determined. And the actual water injection dust effect was tested and analyzed, and achieved better wetting coal and dust effect.
