Good news from the customer unit

Equipment is tailored，Help project construction

Geological Conditions of Xieqiao Mine of China Railway Construction Heavy Industry Co., Ltd. and Huainan Mining Group，After several design liaison and process discussion，The inverted small turn of the main beam is developed and designed.TBM“Guidun No.1”。ThisTBMEquipped with a long lead drilling system、Systematic bolting and temporary support system、Large-slope double-auxiliary boot-supporting system、Panel type hard rock cutter head system with small opening ratio，Olves the problem of large support quantity in the construction of the rock roadway in the coal mine、Mudstone paste knife、Repeated layer penetration and other construction problems，At the same time, it meets the coal safety requirements of the whole machine.，It provides an effective guarantee for safe and efficient tunneling.。

  

“Guidun No.1”TBMOriginating

During the tunneling construction in March，TBMPassing through multiple fault broken surrounding rock interval，Support based on advanced systems、Surplus power reserve and temporary support for targeted design，The steady passage of broken surrounding rock is realized.、The goal of efficient excavation of complete surrounding rock，Creates an open typeTBMA series of records of rock drivage construction in underground coal mine。
