摘要
近年来,瓦斯事故已经成为煤矿安全的"第一杀手"。设计一种通过水力封隔器对近水平孔孔底进行密封的集气装置,对于预防瓦斯事故具有重大意义。该装置通过水力封隔器对钻孔底部进行水力密封,并以纯机械方式自动完成集气。同时进行了室内试验并配合原位瓦斯检测仪进行了现场应用。
In recent years,gas has become the ＂first killer＂ of coal mine safety accident.The gas collecting device to seal by hydraulic packer in the end of the level of the pore.It is a great importance for prevent gas accidents.The equipment hydraulic seals the end of drilling by hydraulic packer,and it gathers gas by purely mechanical means.The indoor experiment and in situ experiment with the in situ gas detector show that this device can be applied in engineering practice.
