Recently, a major effort has been made to develop methods or tools for rock characterization and mineral content mapping. Light detection ranging (LiDAR) is an efficient active remote sensing technique collecting geometry information about surfaces. However, traditional LiDAR sensors work with single-wavelength laser source, it unfeasible obtain spectral using one sensor. The combination of hyperspectral imaging techniques emerging method acquiring spatial simultaneously that allows mapping...
Abstract Coalbed methane (CBM), which is extremely rich in deep coal reserves China, not only the material cause of gas explosion and coal‐gas outburst disasters but also a clean environmentally friendly energy source. Gas drainage must be carried out during mining to avoid accidents while obtaining energy. The low‐level roadway an effective measure for seams with high risk low‐permeability, it can simultaneously realize functions before mining. Roadway tunneling has strong influence on...
An ultrasensitive micronewton force optical sensor based on a tapered fiber Mach-Zehnder interferometer (MZI) embedded in polydimethylsiloxane (PDMS) is studied. Benefited from the methods of non-adiabatic tapering combined with mode field mismatch between different fibers, both which can excite high order modes, achieves sensitivity up to 0.194 nm/mN and low detection limit 103 μN. Meanwhile, this possesses longer effective interference length narrower free spectral range (FSR) than other...
Hydraulic fracturing is a pivotal technology for enhancing reservoir permeability and extensively utilized in the production of coal seam gas. In soft seams, drilling operations can precipitate gas blowouts, forming cavity at base drill hole. However, influence this on initiation propagation hydraulic fractures remains inadequately understood. This study employs discrete element method conjunction with acoustic emission moment tensor algorithm to investigate how angle α—defined as between...
The thick and hard rock strata (THRS) exist widely in coal measure strata, which control the movements of overlying stopes. When THRS break, great energy is released, could aggravate risks gas outburst, burst, other dynamic disasters. Therefore, foundation key preventing disasters are to distinguish that induce coal-rock analyze laws stratum breaking releasing. paper proposed theoretical calculation methods accumulation attenuation greatly affected by hanging length spreading distance. One...
Aiming at the weakness and diversity of signal nano-imprinting pressure to meet requirements detection IPC, a conditioning system software was designed based on Max1452.The achieved data exchange between IPC circuit through RS232.Using acquisition card receive control circuit.The chart showed user interface VC++.Experiment that not only had comparatively high linearity,but also easy use.
In order to solve the problems of complex operation and insufficient environmental adaptability in traditional zero calibration process sight, a fast scheme photoelectric sight is proposed. A rod insertion device based on collimator used image collected by CCD processed this scheme. Through processing method adaptive threshold Canny edge detection Hough transform fitting, feature point acquisition clustering, center position cross obtained, deflection angle between optical axis muzzle...
