Through researching the development of rock-drilling technology, data collection and site surveys, a technical and economic analysis of hydraulic drilling equipment and pneumatic rock drilling equipment for tunnel drilling operations was conducted. The results show that hydraulic drilling equipment

Eprioc Group Company，an emerging company which is split from Sweden'S Atlas Copco，has independent businesses．The family of hydraulic rock drills features complete types and appropriate classification．In this paper,specifications of open-pit hydraulic rock drills from the company are introduced

The structure of a stepwise pressurization device for a full-hydraulic rock drill rig is introduced first,and then the pressure setting method of the device is systematically described. The hydraulic rock drilling rig equipped with the step-by-step pressurizing device can quickly and accurately

The application of 3-boom hydraulic rock drilling jumbos in the construction of passenger-dedicated railway tunnels is presented,analysis is made on the reasons that have impact on the working efficiency of the rock drilling jumbos and some countermeasures are recommended to improve the performance

In order to find out the reason for poor blasting effect in Huashugou mining area of Jingtieshan Mine，and satisfy the need of precision in formation of cutting groove by once middle-deep hole blasting，the tests for improving middle-deep hole drilling accuracy of Simba 1354 rig have been carried out

In light of the problems often incurred by underground mining when ordinary drill jumbos are used, including large deviation between actual borehole locations and the designed ones, poor drilling precision, poor blasting performance and over-or under-blasted face phenomena, the Chambishi Copper Mine

In light of the difference of drilling-blasting construction method and mechanical drilling-blasting construction method in highway tunnel construction，comparatively studies their construction technologies，analyzes differences of artificial drilling-blasting method and jumbo drilling method in

The pillarless sublevel caving method is currently used in Huashugou Iron Mine of Jingtieshan.The adoption of the artificial digging and cutting raise in this method causes high tunneling cost,high labor intensity,poor and dangerous working environment.In order to solve the problems of artificial
