气液联动凿岩钻车应用于露天爆破穿孔

Application of Pneumatic-hydraulic Crawler Drill in Drilling Open-Pit Blast Hole

阐明了气液联动凿岩钻车的主要特点、破岩原理、基本结构、主要技术参数及在露天爆破穿孔中的应用 ,实验表明 ,它具有钻速快、可靠性高、价低、纯钻速约为潜孔钻机的 3- 4倍等优点 ,在露天深孔穿孔作业中具有明显的优势。

The main characteristics, rock breaking principle, basic structure, and specification of pneumatic-hydraulic open-pit crawler drill are discussed. Its advantages have been proved in the open-pit boring test that demonstrates the high boring effciency, (its penetration is 3-4times as high as down-hole crawler drill), high-reliability, and reasonable price.
