全中段一次预锚工艺的研究

Study on the Technical of Securityto Definite Height by Handling

在对接力预锚固工艺缺点分析的基础上,通过深入研究,提出了全中段一次预加固工艺,确定了合理的机械化配套设备,并对经济技术指标进行了对比,从而得出了全中段一次预加固工艺锐减了工人劳动强度,提高了机械化程度和生产效率,有效控制了贫损等各项经济技术指标,社会效益显著。对运用上向水平分层充填采矿法的矿山而言是值得借鉴和推广的。

Based on analyzing of security to staged height by handling ,by penetrate into study ,we put forward the technical of security to definite height by handling ,decided the rational equipment , analyzed and contrast the economical guideline .We draw the conclusion that technical of security to definite height have a series of advantage ,such as small the work labor intensity ,high automatic degree ,high productivity ,lower the loss rate and poverty rate ects.It have certainly social mileage .Thereby ,the technical of security to definite height by handling is worthy consultation and improvement.
