摘要:
六苴矿床深部“刀把”Ⅳ期及“小河-石门坎”急倾斜矿体部分的开采,面临着地热高温、高湿、岩爆多发、通风困难的恶劣的作业环境,会给井下作业人员带来了极的大身心伤害的同时,还使得劳动生产效率急剧下降.而采用常规的落矿方式回采,采切工程量较大,且施工困难,落矿后所形成的采空区空场暴露面积大,围岩容易垮落,生产效率低,贫化、损失严重等问题突出.因此为了解决目前所遇到的困难,可以换一种思维模式,改变一下采场内的落矿方式,及出矿方式.从而寻找到一种科学更有效的方法解决当前所面临的实际问题.
Abstract:
The extraction on the inclined orebody of "Daoba" Ⅳ stage and "Xiaoheng-shimengkan" in Liuju deposit deep section,which is faced with the bad operating environment,such as geothermal high temperature,high humidity,multiple rockburst,ventilation difficulty,which not only brings the extremely large physical and mental harms to the underground workers,and also the labour productivity is dropped sharply.When the conventional ore extraction method is used for recovery,the work amount of mining and development engineering is large,and the construction is difficulty,which can cause the big stope exposure area of goaf after ore extraction,the surrounding rock is easy to collapse,the production efficiency is low,the dilution rate and loss is serious,and the other prominent problems.Therefore,we can change another thinking model,the ore extraction method inside the working site,and the ore removal method in order to solve the current difficulties.Thereby,a kind of scientific and more effective method can be found to solve the current actual problems.
