巷道用履带式深孔钻车属于自行式，主要用于煤矿井下施工全方位、多角度瓦斯

Crawler-type deep-hole drilling rigs for coal mines are self-propelled, mainly used for omni-directional, multi-angle gas discharge holes, water discharge holes, cable holes, and geological data holes for underground construction in coal mines. They can also be used for ground and tunnel engineering drilling. This model was developed by our company to meet the needs of gas drainage and drilling with small diameter shallow holes in coal mines. The drill rig has a crawler walking mechanism, which is highly maneuverable; the hydraulic system is an open circulating pump system. Field tests show that the drilling rig is easy to operate, has good mobility, high drilling efficiency, reliable performance, and drilling positioning and stability, fast and convenient. The crawler is used to solve the time-consuming and labor-intensive problems of relocation. With the increase in mining speed in coal mines, this type of drilling rig has been transformed into a crawler to improve its mobility, reduce auxiliary time such as movement and stability, and reduce labor intensity of workers. Adopting an integral structure, the tubing is not disassembled, the system is not polluted, and the working reliability is high.

The track-type deep hole drilling vehicle used in coal mine belongs to the self-type, mainly used for all-round coal mine underground construction, multi-angle gas discharge hole, discharge hole, cable hole, geological data hole, can also be used for the ground and pit road engineering drilling construction. This model is our company in order to adapt to the current coal mine underground small diameter shallow hole gas extraction drilling needs developed. The drill vehicle has a track walking mechanism and is highly mobile, and the hydraulic system is an open circulation pump system. Field tests show that the drill vehicle is simple to operate, good mobility, high drilling efficiency, reliable performance, drilling positioning and stable fast and convenient. The use of tracks to solve the problem of relocation time-consuming, labor intensity. With the improvement of coal mining speed, the track-type transformation of such drill vehicles, improve mobility, reduce the movement of solid and other auxiliary time, reduce the labor intensity of workers. The use of a holistic structure, the pipeline does not disassemble, the system does not pollute, high reliability of work.

The crawler type deep hole drilling vehicle used in coal mine belongs to self-propelled type, which is mainly used for the construction of all-round and multi angle gas drainage holes, drainage holes, cable holes, geological data holes, as well as the construction of ground and tunnel engineering drilling. This model is developed by our company to meet the needs of small diameter shallow hole gas drainage drilling in coal mine. The drilling rig is equipped with crawler walking mechanism with high mobility; the hydraulic system is an open circulating pump system. The field test shows that the rig has the advantages of simple operation, good mobility, high drilling efficiency, reliable performance, fast and convenient drilling positioning and stability. The crawler is used to solve the problems of time-consuming and labor-intensive. With the increase of mining speed in coal mine, the crawler type of drilling rig is reformed to improve the mobility, reduce the auxiliary time of moving and stabilizing, and reduce the labor intensity of workers. With integral structure, the tubing is not disassembled, the system is not polluted, and the working reliability is high.<br>
