During the construction process,the actual spatial position of the borehole may deviate from the design spatial position,which is called borehole bending or borehole inclination.Hole inclination is one of the six evaluation indicators for drilling,which plays a decisive role in the quality of drilling.The bending of drilling holes is generally influenced by geological formations and drilling techniques.Excessive bending of drilling holes brings difficulties to construction and reduces drilling efficiency,instability of the borehole wall can lead to accidents such as stuck,broken,and buried drilling in the borehole,and what's more serious is the inability to pass through the designed mining points,resulting in the inability to obtain geological data that meets objective reality,causing distortion of the geological situation and affecting the reasonable evaluation of the ore deposit.
