Underground gas drainage drilling construction equipment

1: Developed into a wide-blade spiral drill pipe with high strength, positive and negative rotation, and optimized parameters, such as a triangular spiral drill pipe, so that the drill pipe has the function of cutting the hole wall to deform coal and rock during the rotation process to ensure that the hole does not shrink. At the same time, the drill pipe structure of spiral steel belt or spiral groove forms a favorable channel for mechanical spiral strong slag discharge.

2: The drill bit of easily broken coal mine is developed to prevent large pieces of drilling slag from blocking the slag discharge channel.

3: The use of reasonable parameters of the atomized air pressure slag discharge industry, reduce water damage to the hole wall media, improve the slag discharge speed, to ensure timely slag discharge.
