摘要
煤矿岩石巷道使用中,岩石硬度和破岩方式的选择直接影响施工速度。炮掘工艺具有工艺简单、施工成本低的优点。聚能管光面爆破技术改变常规光面爆破参数,将爆炸产生的能量集中在周边眼连线方向的围岩上,在保证巷道成型质量符合设计要求的前提下,减少对围岩的破坏,保持巷道围岩的完整性。
In the use of rock roadway in coal mine,the selection of rock hardness and rock breaking mode directly affects the construction speed.The blasting technology has the advantages of simple technology and low construction cost.The concentrating tube smooth blasting technology changes the conventional smooth blasting parameters,concentrates the energy generated by the blasting on the surrounding rock in the direction of the surrounding eye connection,reduces the damage to the surrounding rock and maintains the integrity of the surrounding rock of the roadway on the premise that the quality of the roadway forming meets the design requirements.
