摘要
通过对综采放顶煤工作面煤体长孔注水设计的改进,提高了注水后煤体的含水率,并经唐山矿T2193工作面得到验证,煤体注水效果理想。本方案对于降低综放工作面粉尘浓度,改善工人作业环境具有指导作用。
Through the improvement of water-affusing into coal with slotted broach in the synthetical mining caving coal working face, it increase the Containing water of coal bed and the impact is perfect by the validation of the T2 193 working face in Tangshan mine. The seheme has preceptorial function to inducing the dust concentration and improving the job condition.
