为加快坑探工程的进度，降低成本，减轻工人的劳动强度。我队首次使用了KD100型坑道水平钻机，此机加减压、倒杆靠气动和手轮推动双作用进行。地质勘探坑道施工，一般工作量不大，用电动凿岩机掘进较普遍。风动掘进因设备少，成本高，在地质勘探坑道施工中应用较少。因此，为解决KD100型坑道钻机所需气源，我们采用CA—10型解放牌汽车所用汽泵经改装获得成功。经过半年多的生产实践，共完成4个水平钻孔，进尺达250多米，使用效果良好，气压充足可靠，部件改进组装合理，体积小，重量轻，不需另加动力带动，只在钻机的电动机上接出一条三角皮带即可（见附图）。
To speed up the progress of pit exploration projects, reduce costs and reduce the labor intensity of workers. For the first time, our team used the KD100 type tunnel horizontal drilling machine to increase and decrease the pressure. The reverse rod was driven by pneumatic and handwheel to double effect. Geological exploration tunnel construction, the general workload is not large, with electric rock drilling more common. Due to the small number of pneumatic excavation, high cost, less application in the construction of geological exploration tunnel. Therefore, in order to solve the gas source required for the KD100 tunnel rig, we adopted the steam pump used by the CA-10 Jiefangpai Automobile to be rebuilt. After more than six months of production practice, a total of 4 horizontal drilling, into the foot of more than 250 meters, the use of good results, adequate and reliable pressure, improve the assembly of parts reasonable, small size, light weight, without additional power driven only in the rig Take out a V-belt on the motor (see photo).
