Description

Technical Field

[0001] The present invention relates to the technical field of metal mine mining, and specifically to a non-explosive continuous mining and conveying system suitable for soft and broken ore bodies. Background Art

[0002] Under the conditions of soft, broken, highly argillized ore bodies with a high montmorillonite content, conventional blasting mining methods are often inefficient, and serious caving and collapse are prone to occur in the stope, which not only causes resource losses and dilution, making it difficult to achieve the designed production capacity and expected technical and economic effects, but also poses major safety hazards. Due to the swelling of montmorillonite under the action of moisture, situations such as ore adhesion and blockage of the transportation system, and floor heave deformation of the roadway are likely to occur, further increasing the difficulty of mining and transportation.

[0003] In this context, the purpose of the present invention is to provide a non-explosive continuous mining and conveying system suitable for soft and broken ore bodies to solve the problems of low mining efficiency, difficult roadway shaping, easy blockage of the transportation system, and easy damage of trackless transportation equipment in the prior art.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 , the present invention provides a technical solution: a non-explosive continuous ore extraction and handling system applicable to soft and broken ore bodies, and the specific operations are as follows:

[0020] S1. According to factors such as rock abrasiveness experiment, ore-rock stability and ore body excavability, select a non-explosive continuous mining machine with the model SCR200Z.

[0021] S2. According to the mine production capacity and drift layout, select a certain number of electric winch trucks to cooperate with the non-explosive mining machine to continuously extract, handle and transport ore.

[0022] S3. According to the drift layout and the distance of transportation, flexibly arrange a certain number of mobile branch belts and three fixed main belts.

[0023] S4. According to the quantity and positional relationship of the fixed main belts, construct six main ore passes, and arrange vertical belt conveyors or hoisting machines in the main ore passes to transfer the ore to the main transportation level and then hoist it to the surface through the main shaft.

[0024] S5. After each slice of drifts is mined and backfilled, rearrange the stope drifts and fixed main belts according to the positions of the main ore passes, so as to realize the continuous mining, loading and transportation of ore by the non-explosive continuous mining machine, electric winch truck and belt transportation system, and improve the stoping rate and transportation efficiency.

[0025] A certain iron mine adopts the downward drift filling mining method. The stope height is 3.5 m and the width is 4 m. Due to the soft, fractured, argillized ore body with a high montmorillonite content, serious caving and collapse are likely to occur during the stope mining process, it is difficult to form the roadway, and there are major potential safety hazards; moreover, the ore passes are prone to blockage and the rail transportation equipment is prone to damage during the ore transportation process. According to the technical idea of the present invention, the mine adjusts the conventional blasting method to non-explosive continuous mining and loading, and then adopts downward drift stoping, greatly improving the stoping rate and transportation efficiency, and achieving good technical and economic effects.

[0026] In summary, the non-explosive continuous mining and loading system applicable to soft and fractured ore bodies mainly solves the problem of establishing a system for continuous ore stoping and transportation under the conditions of soft, fractured, argillized ore body with a high montmorillonite content, realizing the safe and economic recovery of ore resources that cannot be mined by conventional blasting methods, and improving the ore resource stoping rate and transportation efficiency;
