The solid model was established by the efficiency was greatly improved, Surpac and Zhongwang CAD software, and the middle and deep hole design was carried out by using surpac software .According to the parameters of hole network of scheme 1 and scheme 2, the industrial test is carried out. After

Taking the highway project as an example, the blasting scheme and blasting parameter design are first analyzed, and then the blasting construction technology of high rock slope is studied from the aspects of rock drilling, hole testing, charging, blocking, detonation network connection

Artificial shaft sinking has problems such as high construction risk，slow construction progress and poor construction effect.In order to adapt to the concept of mine safety development and improve the safety and efficiency of the mine building construction patio，the mechanical construction cut patio

With the coal mine gradually moving towards deep mining, the increase of rock burst on the roof and floor of the roadway is followed by the increase of tunneling risk and low tunneling efficiency of hard rock roadway, and the existing roadway deformation is increased, roof caving is prominent and

In the construction of highway tunnel projects, drilling and blasting is the most widely used construction technology. Its main principle is to use explosives to blast for excavation. In the charging process, blasthole drilling is an important part. The use of intelligent rock drilling rigs can

The SimbaH1354 full hydraulic top hammer medium-deep hole drilling trolley produced by Atlas Copco of Sweden adopts EDS electrical direct control system, 12VDC proportional amplifier and potentiometer-controlled electromagnetic proportional control valve for rock drilling propulsion system, and
