| 中文摘要:针对我国煤矿松软突出煤层中的煤巷、高应力巷道等小断面巷道，以及皮带运输巷中钻机需频繁让道、在掘进巷道中钻机需绕前施工等通过空间狭小的复杂钻孔施工条件，结合煤矿钻孔现场施工对孔比较繁琐及搬运迁移比较困难的现状，进行了ZLY2500L型煤矿用履带式坑道钻机的研制。目前常用的整体式履带钻机大多存在不能将井下机动灵活、外形尺寸小、操作人员安全性高等特点高度融合的缺陷，导致瓦斯抽采钻孔施工效率低，钻机对复杂钻场和矿井条件适应性差。该机型结构布置合理，辅助功能齐全，它能有效地改善中小煤矿钻孔施工效率，提高钻掘产量，降低工人劳动强度，可用于瓦斯抽采穿层钻孔、瓦斯抽采顺层钻孔和探放水以及底板注浆等钻孔施工。本文主要介绍ZLY2500L型煤矿用履带式坑道钻机的主要技术参数、结构布局特点及液压系统。经试验表明，对于中小煤矿钻孔施工具有良好的应用前景。 |

| Abstract:In view of the coal roadway， the high stress roadway and other small section roadways in the soft outburst coal seams in China’s coal mines， as well as the complex drilling conditions in narrow space， such as frequent giving way in the belt transportation roadway， by-passing of the roadway at work by the drill， and in light of the existing difficulties in movement and alignment of the drill in the coal mine drilling field， ZLY2500L crawler tunnel drill for coal mines is developed. At present， the commonly used containerized crawler drill has such defects： it can’t highly integrate underground mobility， compactness and high safety for operators； thus， leading to low gas drainage drilling efficiency， and poor adaptability to the complex drilling field and mine conditions. ZLY2500L drill can effectively improve drilling efficiency in small and medium-sized coal mines， increase mining output and reduce the labor intensity. It can be used for cross-seam and in-seam gas drainage drilling， water exploration and drainage， floor grouting and other drilling work. This paper mainly introduces the main technical parameters， the structural layout features and the hydraulic system of ZLY2500L crawler tunnel drill for coal mines. The test shows that it has a good application prospect for drilling in small and medium-sized coal mines. |
