【摘要】 介绍了煤层注水技术在芙蓉煤矿的研究与应用,提出了适合芙蓉煤矿特点的注水参数,如注水压力为4.425~7.2 MPa,注水时间以煤壁"挂汗"时为止,还介绍了钻孔布置方式以及注水工艺,为芙蓉煤矿治理瓦斯、防治煤炭自然发火、减小粉尘危害探索出了新的途径和方法,并对该矿今后的防灾治灾工作提供了指导。更多还原

【Abstract】 The paper introduced the research and application of the in-seam water injection technology to Furong Mine.The paper provided the water injection parameter suitable to the mine features.The water injection pressure was 4.425～7.2 MPa and the water injection time would be ended when there was "sweating" on the coal wall.The paper also introduced the borehole layout method and water injection technology.All above have provided the new access and method of the mine gas control,coal spontaneous combustion control and dust control for Furong Mine and would be a guidance for the mine disaster prevention and control of the mine in future.更多还原
