This invention discloses a ore body cutting scanning feedback mechanism, comprising an ore body information acquisition module and a cutting information acquisition module. The ore body information acquisition module is used to collect ore body information of the target ore body, including its material composition and hardness coefficient. The cutting information acquisition module is used to collect cutting data during the ore body cutting process, including target distance, cutting depth, and cutting width. An ore body cutting system and method with the above-mentioned ore body cutting scanning feedback mechanism are also disclosed. This system enables accurate, rapid, and intelligent identification of ore body properties before cutting and real-time feedback during the cutting process, improving the rock-breaking accuracy of abrasive waterjet and reducing ore loss.

This utility model discloses a water jet mining device suitable for physical fluidized bed mining, including a mechanical extension arm coal breaking unit, a high-low pressure water circuit control conversion unit, and a positioning and reset unit. The mechanical extension arm coal breaking unit includes a jet support body, a hollow shaft, and a mechanical extension arm. The high-low pressure water circuit control conversion unit includes a high-low pressure conversion valve core, a control spring, and a seal, all coaxially installed within the jet support body. The positioning and reset unit includes a reset torsion spring and a drill pipe connection joint. This water jet mining device suitable for physical fluidized bed mining is small in size, highly mobile, and flexible. Utilizing the mechanical extension arm for borehole enlargement can effectively increase the coal breaking volume and gas extraction concentration per borehole, enabling safe and efficient underground co-mining of coal and gas using fluidized bed technology. It is particularly suitable for coal and gas mining operations in gas-bearing mines.

This utility model discloses a hydraulic punching processing equipment, belonging to the technical field of hydraulic punching equipment. The structure includes a water supply tank, a connecting pipe, a hydraulic punching control group, and a hydraulic punching device. The device adopts an independently installed structure for the hydraulic punching control group. By separating the control components from the punching execution components, the complexity of the device's debugging process is effectively reduced, and the hydraulic punching-related parameters can be adjusted more conveniently, greatly improving the ease of use of the device. Simultaneously, the device optimizes the structure of the water supply tank by setting up an independent output water pump, thereby more precisely controlling the water flow output from the tank and improving the accuracy of the hydraulic punching.

This invention relates to the field of decorative stone mining technology, and more particularly to a high-efficiency, low-damage mining method for hard stone. The invention provides a high-efficiency, low-damage mining method for hard stone, comprising the following steps: dividing the hard stone mining area into zones and then drilling holes; sequentially applying microwave radiation excitation, high-pressure jet cutting, and carbon dioxide blasting to the hard rock mass in a predetermined fracturing direction. This mining method overcomes the problems of traditional rock explosive blasting, such as difficulty in controlling energy, high risk, large vibration effects, and significant damage to the internal structure of the stone, as well as the severe wear and low production efficiency of wire saws in hard stone mining, thus achieving high-efficiency, low-damage mining of hard stone.

The present application belongs to the technical field of deep-sea mineral resources mining, and specifically relates to a deep-sea polymetallic nodule collection equipment, comprising a vehicle body; characterized in that the vehicle body is provided with a double-row jet flow collection system and a storage bin; the double-row jet flow collection system comprises a main jet flow head and an auxiliary jet flow head; the main jet flow head and the auxiliary jet flow head are configured to work synchronously, jointly disturb the nodule layer of the seabed, and make the nodules move directionally; and the storage bin is used for storing the collected nodules. Through the synchronous working of the main jet flow head and the auxiliary jet flow head, the main jet flow head is used for crushing and loosening the nodule layer in the deep layer, the auxiliary jet flow head synchronously generates a low-disturbance auxiliary jet flow to inhibit the backfilling of sediments, and the two form a synergistic jet flow field, so that the disturbance capacity can be ensured, the nodule stripping time is prolonged, and the collection rate and overall productivity are improved.
