A series of evidences obtained from field research has proved that the Hunhe fault zone, which runs across the downtown region of city Fushun and the Fushun Petroleum Refinery No. 1, exhibits no any apparent recent movement. For example: 1. the age of the youngest fault activity underneath the refinery region has been measured by thermoluminescent dating of fault gouge as 261, 900+26050 yr; 2. the Hunhe rioter terraces on both sides of the fault valley have been as eertained as having the same number of levels and exhibiting no obvious vertical dislocation; 3)seismic activities along the fault zone are found to be very weak, with only micro-earthquakes occurring very scarcely. In addition, the vertical displacement along the fault zone revealed by geodetic measurement and levelling survey in recent 10 odd years in the refinery region is over 600 times larger than that in regions east and west of it. The characteristics of land deformation and the nature of ground fissures occurring in the southern part of the refinery, which is located right on the northern margin of the Fushun open pit coal mine, have been identified to be the result of local landslide and subsidence. All the above-stated facts taken together indicate that the land deformation and ground fissures in the refinery region are not the consequence of recent fault activity but that of the northward mining in the open pit.
