Abstract The relationship between stress and drill cutting weight (DCW) is studied with numerical modeling and field testing. Jinjiazhuang coal mine 110403 workface is used as a case study. Stress analysis of the workface is carried out with numerical modeling, with input parameters obtained from laboratory experiments. The stress of workface is examined at one section along the mining direction in terms of the stress distribution. Comparing simulating results of stress and field testing drill cutting weight, the stress and drill cutting weight has good agreement and one formulation is derived in this case.
