1. The methods of developing groundwater wells include (a) drilling wells extending to the interior of rock formations; 1. Each borehole is drilled from the starting point of the first borehole end to the end point of the second borehole end; (b) the borehole is filled with alternating layer explosives and back material to produce multi-layer explosives; Through and into training, including at least one layer of blasting equivalent to the end of the rail head and one last layer equivalent to the second end of the rail.Each explosive layer has a wireless explosive device; and (c) on the basis of the explosive layer, by detonating the wireless explosive device on each explosive layer, the explosive is detonated in a series of explosive stages. From the first blasting to the last blasting, after each blasting stage, excavation will be carried out in the so-called direction to extend the length of the oil well.
