Abstract: A simulation test system for gas extraction from a tectonically-deformed coal seam in-situ by depressurizing a horizontal well cavity. A coal series stratum structure reconstruction and similar material simulation subsystem simulates a tectonically-deformed coal reservoir. A horizontal well drilling and reaming simulation subsystem constructs a U-shaped well in which a horizontal well adjoins a vertical well, and performs a reaming process on a horizontal section thereof. A horizontal well hole-collapse cavity-construction depressurization excitation simulation subsystem performs pressure-pulse excitation and stress release on the horizontal well, and hydraulically displaces a coal-liquid-gas mixture such that the mixture is conveyed towards a vertical well section. A product lifting simulation subsystem further pulverizes the coal and lifts the mixture. A gas-liquid-solid separation simulation subsystem separates the coal, liquid and gas. A monitoring and control subsystem detects and controls the operation and the execution processes of equipment in real time.

Abstract: A method for extracting and correcting a ringing component in a dynamic pressure measurement signal of a shock wave flow field includes: adaptively decomposing a dynamic pressure measurement signal of a shock wave flow field through an empirical mode decomposition (EMD) method, and extracting a ringing component in the dynamic pressure measurement signal of the shock wave flow field; constructing a ringing component distortion correction model through a convolutional neural network (CNN) and a dataset through a staggered spanning dataset construction method; and predicting a time series of a segment with mode mixing in the ringing component, to accurately extract a ringing component in a dynamic pressure response signal. The method combines advantages of an adaptive signal decomposition method and a CNN model identification method.

Abstract: A dispersant for premixed fluidized solidified soil includes the following raw materials in parts by weight: 5 parts to 15 parts of an anti-adhesion water reducer, 0.5 parts to 0.8 parts of a stabilizer, and 85 parts to 95 parts of water. The anti-adhesion water reducer is compounded by an inorganic dispersant and an aminosulfonic acid-based superplasticizer (ASP), and the inorganic dispersant is at least one selected from the group consisting of sodium silicate, sodium hexametaphosphate, and sodium pyrophosphate. In the present disclosure, on the premise of improving fluidity of mucky cohesive soil slurry, a strength of the fluidized solidified soil at each stage is adjusted through a water-reducing effect of the anti-adhesion water reducer. Moreover, rapid dispersion of the mucky cohesive soil slurry is realized, thus providing key technical support for preparation of the premixed fluidized solidified soil from undisturbed soil in non-dry conditions.
