Nxburst™ Safety Cartridges are propellant-based cartridges that produce a controllable blast suitable for Rock Breaking and Concrete Breaking in envionrmentally sensitive conditions.
Experiment and Simulation of the Shape and Stored Gas Characteristics of the Flexible Spherical Airbag for Underwater Compressed Air Energy Storage
Tunnel energy storage refers to a method of storing energy by utilizing underground tunnels, typically from decommissioned or unused mining structures, to hold kinetic energy or potential energy in water or compressed air.
We propose a multi-functional polyvinyl alcohol (PVA) – NaCl @ Polyaniline (PANI) (PNP) hydrogel, which is characterized by easy fabrication, integrated structure, and flexibility, and can be directly applied in the fields of

Deeper and longer tunnels are developed to meet the demands of transportation, energy storage, shelter, dwelling, and so on. However, deep rock mass excavation and construction present a great number of challenges, which urgently need to be addressed, such as rock bursts and squeezing.
Few scholars have carried out theoretical research on energy evolution for deep soft rock tunnels. This study proposes a computational method for tunnel energy evolution in strain-softening rock mass during excavation unloading based on triaxial stress paths.
This paper presents an alternate method of underwater energy storage utilizing an object''s inherent buoyancy as a means for storage known as buoyancy battery energy storage (BBES). Utilizing a simple pulley, reel and float mechanism,
Addressing the issues of short target distance and small nozzle diameter in conventional jet rock breaking, which result in low rock breaking energy and difficulty in achieving efficient rock fragmentation, a high-pressure energy-gathering water jet
It is an object of the present invention to provide at least an alternative underwater energy storage system, which provides improvements over known underwater energy storage...
