摘　　要：为了保证金川集团可持续发展,需要对二矿区“采富保贫”开采方针保留下来的1100m水平以上的贫矿资源进行开发,而通风保障是贫矿开采的重中之重。因西侧进风段相对风阻较大,风压较小,使得东西二侧进风风量失衡。另外,回风段风阻较大,风压较小,也使得回风不畅,将造成贫矿开采工程通风困难,严重影响其安全生产。因此,经过调查研究,决定在西侧2行风井井口、16行充填井井口分别新建地表风机站,采用压抽混合式通风方式为贫矿开采工程提供通风保障。In order to ensure the sustainable development of Jinchuan Group,it is necessary to develop the lean ore resources above the 1100m level retained by the mining policy of"mining rich and protecting poor"in No.2 Mine,and ventilation guarantee is the top priority of lean ore mining.Due to the large relative wind resistance and small wind pressure of the west inlet section,the air volume of the east and west inlet is unbalanced.In addition,the wind resistance of the return air section is larger and the wind pressure is smaller,which also makes the return air is not smooth,which will cause the ventilation dfficulties of the lean ore mining project and seriously affect its safety production.Therefore,after investigation and research,it is decided to build a new surface fan station in the west side of 2 rows of air shaft wellheads and 16 rows of flling well wellheads,and adopt the pressure pumping mixed ventilation mode to provide ventilation support for the lean ore mining project.
