摘要
根据高瓦斯矿井瓦斯抽采钻孔施工特点及要求,研制了ZDY4000LF型两体式履带钻机。钻机结构新颖、功能齐全、操作便捷、体积小、机动性强,满足矿井的防突要求,钻机仰俯角、方位角和水平开孔高度调节范围大,适应顺层孔和穿层孔等多种钻探施工工艺。
ZDY4OOOLF split type caterpillar drill was developed successfully according to the requirements of high - gas coal mine gas drainage drilling and construction characteristics. The drill has many advantages, such as small size, novel structure, complete func- tion, simple operation, power maneuverability and suitable for gas control in high gas mine. The drill has a larger regulation range of elevation angle, the agimuth angle and drilling hight. Drilling techniques can he suitable for bedding holes and through beds holes.
