Hitting the pain point: Hard rock excavation without blasting
In coal mines, metal mines and tunnel projects, hard rock excavation has long been a major challenge. Traditional Drilling Rigs rely on blasting after drilling, which is not only strictly approved and has a high risk factor (vibration, flying rocks, dust), but also inefficient and cumbersome. Are you troubled by blasting ban restrictions, safety risks, and serious delays in excavation progress? ZYT-90 drilling and expansion integrated drilling vehicle is your weapon to break the deadlock!
As a revolutionary Drilling And Splitting Machines, ZYT-90 creatively combines efficient rock drilling and non-blasting static splitting. It abandons traditional blasting and inefficient Excavator Converted Drilling Rigs (excavator converted drilling rigs), and directly completes the continuous operation of drilling → inserting expansion rods → static splitting on the airborne platform. Field measurements show that in hard rock with f=8-12, the single-cycle excavation depth is significantly improved, the risk of blasting is completely avoided, noise and dust are greatly reduced, and safe, efficient and continuous non-explosive excavation is truly achieved!
Its application scenarios are extremely wide:
Core scenarios: Coal mine/metal mine hard rock tunnels, railway and highway tunnels, water conservancy and hydropower tunnels, and isostatic environment hard rock excavation.
Fine work: precise shaping of tunnel ditches and safe expansion of underground refuge chambers.
Auxiliary processing: secondary splitting of large ore, breaking of foundation pit rocks, and opening of emergency rescue channels.
ZYT-90 drilling and expansion integrated drilling vehicle core value:
Safety revolution: completely bid farewell to blasting and eliminate safety hazards.
Efficiency leap: continuous drilling and splitting, and significantly accelerated excavation progress.
Widely applicable: From large tunnels to fine engineering, one machine has multiple functions.
Product features and tips:
Dual-effect integration: A single device integrates rock drilling and static fracturing, seamless switching, reducing equipment investment and transition time.
Safe and controllable: Pure mechanical splitting, no blasting shock waves, flying stones, minimal disturbance to the surrounding rock, especially suitable for sensitive areas (such as near residential areas, existing buildings, high gas environment).
Flexible adaptation: According to different hard rock strength and excavation requirements, flexible adjustment of drilling parameters (aperture of about 45-90mm) and splitting point arrangement.
Continuous operation: Realize the process of drilling-loading-splitting, greatly improving the efficiency of tunnel forming.
Tips:
Hole spacing optimization: The key to the splitting effect lies in the design of drilling hole spacing and row spacing. According to the hardness and texture of the rock, the hole spacing of 30-50cm is generally recommended (on-site test fine-tuning is required). Too dense is wasteful, and too sparse affects the splitting effect.
Hole depth control: Make sure the drilling depth is greater than the required splitting depth, usually 10-15cm deeper, to ensure that the expansion rod can fully exert its wedge force and avoid "stuck".
Choosing ZYT-90 means choosing a safer, more efficient and more compliant future for hard rock excavation! Say goodbye to the shackles of blasting and release the potential of excavation.
