“煤层打钻防灭火装置”是在井下打钻现场应用的一套全自动、智能化灭火装置,能够快速、有效控制和消除钻场、钻孔初期火灾,防止钻孔火灾事故进一步扩大和现场人员中毒现象发生。随着我国煤矿井工开采深度不断加大,矿井开采条件越来越差,制约矿井安全生产的因素越来越多,特别是瓦斯因素严重影响着矿井的安全生产。在实际生产中,大部分矿井采用施工瓦斯钻孔来解决瓦斯事故危险,但在施工钻孔过程中,时常出现顶钻、夹钻、钻杆发热甚 “Coal seam drilling fire-fighting prevention device ” is a set of automatic and intelligent fire-extinguishing device applied in the underground drilling site, which can quickly and effectively control and eliminate drilling field, initial drilling fire and prevent drilling fire accident from further expanding And on-site personnel poisoning occurred. With the deepening of coal mining in China, mining conditions are getting worse and worse, and more and more factors restrict the safety of coal mines. In particular, gas factors seriously affect the safety of mines. In actual production, most of the mines use construction gas drilling to solve the danger of gas accidents. However, during the construction drilling process, top drilling,
