Abstract: A device for on-site detection of soil organic matter, including a pre-processing module, a centrifugal system, a microfluidic chip, and a photoelectric detection module. The pre-processing module is configured to process a soil sample into a soil solution. The centrifugal system is configured to generate a centrifugal force. The microfluidic chip is configured to allow mixing of the soil solution and an extraction solvent for extraction under the centrifugal force to obtain an extract. The photoelectric detection module is configured to detect the extract to determine organic matter content in the soil solution. An on-site detection method and a microfluidic chip are also provided. The microfluidic chip includes a channel layer, a cover layer arranged above the channel layer, and a base plate layer arranged below the channel layer.

Abstract: A device for detecting soil nutrients on site, including an extracting grid, an on-site real-time detection assembly and a transfer assembly for transferring a soil extract from the extracting grid to the on-site real-time detection assembly. A soil nutrient detection method using the device and a microfluidic chip are also provided. The microfluidic chip includes a cover plate and a base plate. The base plate includes a soil extract feeding groove, a quantitative feeding groove, a reagent storage groove, and a serpentine groove.

Abstract: For the problem of difficult roof anchor withdrawal at the end of a working face, a static crushing directional anchor withdrawal method at the end of a large-mining-height working face is provided. The method includes the following steps: designing key parameters of boreholes for static crushing, including a borehole position, a spacing between boreholes, a borehole depth, and a borehole diameter at the end of a working face; then determining parameters of a static crushing agent grouting technology device for the construction of a static crushing process; and carrying out an anchor withdrawal operation at the end.
