缓倾斜极薄矿脉控制爆破技术及其模糊综合评价

Control Blasting Technology of the Gently Inclined & Thin Ore Vein and a Fuzzy Mathematical Comprehensive Evaluation on the Blasting Effect

针对缓倾斜极薄矿脉开采贫化率大、出矿困难和顶板安全性差等问题,在该类型矿脉的开采中采用控制爆破技术取得了良好的效果,而合理的选择爆破参数可最大限度地减少爆破对顶板岩石的破坏、降低贫化率和维护采场顶板的安全。笔者以某缓倾斜极薄矿脉开采为例,对缓倾斜极薄矿脉开采进行了控制爆破技术研究,并应用模糊数学模型对爆破效果进行模糊综合评价。其研究结果对缓倾斜极薄矿脉的开采具有重要意义。

Considering the existing mining technological conditions of the control blasting technology is of great significance in reducing roof rock gently inclined and thin ore vein, the damage and cutting down ore dilution. The deliberate and reasonable choice of blasting parameters can achieve ideal blasting effects. Taking a gently inclined and thin ore vein as the example, this paper studies the effects of control blasting. A fuzzy mathematical model is practiced to evaluate the blasting effects. The research is of great reference significance to the mining of the gently inclined and thin ore vein.
