摘　　要：为顺利开采某矿区+448中段的复杂破碎钨矿体,提出了底部结构预支护的水平深孔留矿法开采技术方案。方案采用脉外采准、水平扇形炮孔崩矿、采场留矿、中空锚杆注浆和光面爆破等技术,可有效解决底部结构布置、炮孔施工与易错位和围岩稳定等开采难题。In order to exploit the complex crushed tungsten ore body in ＋448 middle section of a certain mining area, the papter puts forward a mining technical option with horizontal deep-hole shrinkage mining that has pre-support of bottom structure. This option adopts stope preparation outside the vein, ore caving with horizontal fan-shaped blast hole, stope shrinkage, grouting with hollow anchor rod, smoothing blasting, and other technologies. It can effectively solve the mining difficulties like bottom structure arrangement, blast hole construction, easy dislocation, and adjoining rock stability, etc.
