Application of Directional Drilling Technology for Water Exploring and Discharging in Roof of Muduchaideng Coalmine

Abstract:

Flooding is one of the three major dangers that threaten the safety production in coal mine. Exploring and discharging borehole construction is an important means to prevent and deal with flooding. The article elaborates the construction process of exploring and discharging borehole with directional drilling technology. The practice proves that by means of the directional exploring and discharging borehole, water information of target area may be accurately detected, which meets the requirements of water exploring and discharging in mine and provides technical support for safety production.
