Abstract: The underground mined-out area in Zhaoyuan Area has the characteristics of complex distribution and unclear occurrence, which seriously restricts the safe and efficient production of mine. Taking the near-surface thin vein mined-out area of Lingshan Gold Mine as the research object, the actual situation of the mined-out area is initially mastered through mine field investigation. Based on engineering geophysical exploration and drilling technology, five geophysical exploration lines and one verification borehole are arranged in the surface of the key investigation area to effectively explore and verify the occurrence state of the mined-out area. On this basis, the mechanical characteristics of the filled waste rocks were obtained based on the laboratory test, and the distribution law of stress field and displacement field of surrounding rock in the typical mined-out area is obtained by numerical analysis. Ultimately, based on the mine status and existing research results, the near-surface mined-out area stability evaluation is carried out, which makes a comprehensive analysis of the mined-out area state and the overlying rock stability. The results show that the occurrence state of near-surface mined-out area is good, and waste rocks has been effectively filled, which is in a stable state and does not cause surface stability problems. Meanwhile, the research results obtained by various exploration methods are basically the same, which is consistent with the mine data. The buried depth of the mined-out area obtained by geophysical exploration and drilling methods is 54.27 m and 55.70 m, respectively. It is inferred that there are one class I and five class II mined-out area abnormal areas with medium and low resistivity. The waste rocks filled in mined-out area has obvious strain hardening characteristics, and its internal friction angle and cohesion are 42.1° and 96.0 kPa. Aiming at the problem of unclear occurrence state and stability of near-surface thin vein mined-out area, a complete set of comprehensive exploration methods and stability evaluation technology of near surface mined-out area was formed, which realizes accurate exploration and evaluation of mined-out area state. The research results have important reference for the exploration and evaluation of underground mined-out areas in Zhaoyuan Area.
