In order to analyze No. 2 mining area roadway stress of No. 3 coal seam in Yechuan Mining Industry, field measurement was adopted. Based on supporting form and supporting parameters of roadway, four basis points for 1.0, 1.8, 3.0 and 8.0 m of the roof was designed, two sides 1.0, 1.8, 3.0, 4.0 m four point type, the first mining affecting the initial anchoring force of roadway anchor cable construction met the needs, the initial anchoring force of roadway construction affected by secondary mining can reach the requirement, the initial anchoring force of driving and primary mining anchor cable was large, but the final stability valuewas generally smaller than the initial anchoring force, and generally the final stability ywas between 3 ~ 6 t. The construction quality of anchor rod was basically up to standard. The force of primary and secondary mining anchor rod was relatively large, while that of top anchor rod in roadway was relatively small. The force of upper anchor rod does not exceeded 2.6 t. During the observation period, the force of anchor cable was basically stable, while the force of anchor bolt was still changing, which indicated that the anchor rod had great supporting effect of the mining recovery and strong adaptability to the force change.
