This study used a digital drilling test system to conduct experiments on layered rocks with weak interlayers, monitoring drilling parameters and borehole sound pressure and vibration acceleration in real time. Time-domain and frequency-domain features of borehole sound pressure and vibration. .
Vibro-Impact Drilling (VID) is a promising efficient rock-breaking technology in hard-rock drilling. This technology is designed to break rock with vibration or impact loads and its ultimate goal is to break rock in resonance state. Characteristics of viscosity and density have a significant.
[pdf] Exploration drilling projects in arctic and northern regions often take place in remote, cold, isolated and demanding locations such as lakes, muskeg areas and oceans. One of the major challenges for these projects is the lack of infrastructure making it unfeasible to employ barges or drilling vessels to support project. .
Ice pads can be grounded or floating depending on the water depth and the ice thickness required to support the intended loads. The design load should account. .
Ice pads can be constructed by free-flooding, with spray ice or with chipped ice. Typically, free-flooding is the most cost effective construction method however. .
The bearing capacity of the ice pad depends on the quality of the constructed ice. Proper construction procedures must be employed to ensure the highest ice.
