东风—25型电动凿岩机是浙江龙游探矿厂和勘探技术研究所研制的一种新型凿岩设备。它具有重量轻、搬迁容易、结构简单、操作方便、设备利用率高和成本低等优点。我局二、五、十八等八个地质队曾先后采用这种设备在3—8级岩矿层中掘进水平巷道3800余米。实践证明，在中硬和坚固岩层中掘进，效果较好，在正常生产的情况下，每米的成本仅80元左右。受到广大坑探工人的好评。
Dongfeng -25 electric rock drill is a new type of rock drilling equipment developed by Zhejiang Longyou Prospecting Factory and Exploration Technology Institute. It has the advantages of light weight, easy relocation, simple structure, convenient operation, high equipment utilization and low cost. My bureau two, five, eighteen eight geological team has successively used this equipment in level 3-8 rock tunnel digging horizontal road 3800 meters. Practice has proved that in the hard and solid rock tunneling, the effect is better, in the case of normal production, the cost per meter is only 80 yuan. Be pitched by the vast majority of pit workers.
