The invention provides a gas extraction directional drilling system and equipment. The gas extraction directional drilling system comprises a steering structure, the steering structure comprises two propelling parts, a transmission part is arranged between the two propelling parts, steering assemblies are arranged on the two sides of the transmission part, and a tunneling structure is arranged on the outer side of one propelling part. Through the arranged steering structure, the direction of the tunneling structure is adjusted in the drilling process, so that the drilling direction is changed, and an extraction hole with a large radian is formed. 本申请提供了一种瓦斯抽采定向钻孔系统及设备，包括转向结构，所述转向结构包括两个推进部，所述两个推进部之间设有传动部，所述传动部的两边侧均设有转向组件，其中一个推进部的外侧设有掘进结构。本申请通过设置的转向结构，实现了钻孔过程中调整掘进结构的方向，从而改变钻孔的方向，实现形成具有较大弧度的抽采孔。
