Description
Technical Field
[0001] The invention relates to the technical field of mining industry, and in particular to a prospecting and mining method combining exploration and mining of a Jiwo mine. Background Art
[0002] At present, the mining of "Jiwo Mine" is mainly based on the delineation of the ore veins by the early sparse drilling project, and the ore veins are exposed by the main penetration development method, and then the ore veins are controlled along the veins through the vein engineering. The scale and continuity of the ore body are evaluated by the ore-seeking along the veins at the upper and lower middle elevations, which serves as the basis for the layout of the ore body mining project; the mineralization of the ore veins is extremely unstable in terms of strike and dip, and the ore bodies are mostly pod-shaped. The ore-seeking along the upper and lower veins and along the veins is not enough to serve as the basis for the overall scale and continuity of the ore body. Therefore, there is often great uncertainty in the mining process, resulting in serious problems of ore body depletion and loss in the mining field.
[0003] At the same time, for the mining and cutting project of the "Jiwo Mine", due to the large uncertainty of the "Jiwo Mine", the upper and lower middle sections of the veins are not enough to fully control the actual shape of the ore body. This leads to the mining project we designed may cause large ore losses or depletion problems in the actual mining process. For example, after the mining project is arranged, ore is found outside the mining project. It is economically unreasonable to arrange the mining project again due to the small resource volume. This leads to waste of resources in the corner ore bodies. If ore is found inside the mining project, it will lead to unnecessary waste of the project. Therefore, in actual engineering applications, loss and depletion problems are one of the main reasons affecting the economic benefits of domestic "Jiwo Mine" mining enterprises.
[0004] With the promotion of mine mechanization and the improvement of mining efficiency year by year, the service life of Jiwo ore body mining is shortened, and the high-quality exploitable resources are gradually reduced. If the mining field resources are not recovered in place and the goaf has been formed, it is difficult to utilize the unrecovered resources. If the mining is blindly followed up or the exploration is extended at both ends, it may cause huge depletion and even lead to the failure of resources to achieve economic benefits. These problems seriously restrict the sustainable development of mining enterprises with rich Jiwo ore. To this end, we propose a prospecting and mining method that combines exploration and mining of Jiwo Mine. Summary of the invention
[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a prospecting and mining method that combines exploration and mining of Jiwo mine, which can improve the comprehensive utilization of mineral resources, reduce prospecting costs, alleviate prospecting pressure, extend the mine service cycle, and effectively solve the problems in the background technology.
[0006] To achieve the above object, the present invention provides the following technical solution: a method for combined exploration and mining of Jiwo Mine, comprising the following steps: S1) Exploration of ore body characteristics: Arrange intensified drilling projects for the project ore bodies through the delineated geological ore bodies, and carry out blind mid-section pit exploration projects when necessary to further clarify the occurrence of the ore bodies and study the characteristics of the Jiwo ore body; S2) Digital processing and analysis: Collect and digitize all geological data of the mining site, including geological cataloging data implemented at each stage, spatial location of goaf, ore-seeding conditions in ventilation shafts, laboratory analysis data, on-site data on surrounding rock stabilization, and digital processing of shaft, tunnel and tunnel engineering data, and then use Micromine, ArcMap and CAD software for visualization and mathematical geological statistical analysis; S3) Arrangement of mining projects: Select reasonable mining methods according to the occurrence of the project ore body, and then flexibly arrange some exploration and mining projects (i.e., through construction extension, cutting wells, high-pass wells) to recover all resources in the mining process to achieve maximum resource recovery; S4) During the mining process, due to the uncertainty of the Jiwo Mine, it is necessary to extend or shorten the mining area of the Jiwo ore body to reduce the waste of ineffective projects and achieve the maximum economic benefits.
[0007] As a preferred technical solution of the present invention, in step S1), the characteristics of the ore body are mainly explored by drilling and pit exploration.
[0008] As a preferred technical solution of the present invention, the drilling in step S1) mainly utilizes a small drill in the pit (usually less than 100 meters) to drill holes in or around the encircled ore block to check the shape and form of the unmined ore body.
[0009] As a preferred technical solution of the present invention, in the step S1), tunnels are dug manually or by small machinery at locations in the Jiwo mining area where the cover layer is thin and has good continuity, so as to directly observe and study the geological structure and the occurrence of the ore body.
[0010] As a preferred technical solution of the present invention, in step S3), the upper and lower middle sections are discontinuously mineralized according to the prospecting results. In the original traditional backfill mining method, high chute and secondary middle section supplementary mining projects can be added to achieve maximum recovery and utilization of resources.
[0011] As a preferred technical solution of the present invention, in the step S3), considering the geological characteristics of the study area, the complex branching of ore veins is relatively common. In the backfill mining method, extended prospecting can be added. At the same time, the transportation route can be optimized in combination with the characteristics of the original mining site to improve the resource recovery rate.
[0012] As a preferred technical solution of the present invention, in the step S4), when ore is found at the end of the mining area, an economic analysis of extended construction is conducted based on the grade of the ore. If it is economically feasible, a 1.2*1.8 extended cutting tunnel is constructed until there is no ore.
[0013] As a preferred technical solution of the present invention, in the step S4), when the mining effect at the end of the mining field is poor, or there is no mineralization at a certain distance from the end, it is necessary to analyze whether the mining field can be shortened based on the previous prospecting project. If the mineralization of the end cannot be judged based on the previous construction project, a cutting well or cutting tunnel can be constructed at the end of the mining field to explore the distribution of the non-ore area, and then an economic analysis can be carried out.
[0014] Compared with the prior art, the beneficial effects of the present invention are: according to the mineralization characteristics of the Jiwo Mine mining site, an effective exploration and mining project is formed, and the mining and cutting project is improved in combination with the basic characteristics of the original project. At the same time, in the process of mining, the mining method selected is combined to further improve the mining and cutting project, which can improve the comprehensive utilization of mineral resources, reduce prospecting costs, alleviate prospecting pressure, and extend the mine service cycle. At the same time, mining enterprises can adopt personalized mining plans according to the geological characteristics of the mine, the properties of the ore, the terrain conditions, etc., to achieve the best mining effect, which meets the humanized requirements of green mine construction. In terms of technological innovation and process upgrading, it can improve the production efficiency of mining enterprises, reduce production costs, and promote the sustainable development of mines. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic diagram of the process of the present invention; Figure 2 This is a schematic diagram of a stope according to one embodiment of the present invention. DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] See also Figure 1-2 The present invention provides a technical solution: a prospecting and mining method combining exploration and mining of Jiwo Mine, which arranges intensified drilling projects for the project ore body through the delineated geological ore body, and constructs blind middle section pit exploration projects when necessary to further clarify the occurrence of the ore body, and selects a reasonable mining method according to the occurrence of the project ore body, and then flexibly arranges some exploration and mining projects (i.e., through the construction of extensions, cutting wells, and high-pass wells) in the process of mining to recover all resources, so as to achieve maximum resource recovery.
[0018] In the Qiaogou mining area of the Yuelianggou mining area, the main mining methods currently used are the shallow hole chute method, the wall cutting and filling method, the subsequent filling method and the chamber filling method; among them, the wall cutting and filling method and the subsequent filling method are the most commonly used; and they are also relatively flexible, which can effectively avoid losses and depletion problems; therefore, the mining design and mining method selection of the Jiwo Mine are also crucial; at the same time, combined with the company system, the goal of maximizing economic benefits can be achieved.
[0019] Specifically, the following steps are included: first, technical means are used to ascertain the initial occurrence of the ore body in the ore block, and the characteristics of the Jiwo ore body are studied, mainly through drilling and pit exploration methods to explore the characteristics of the ore body; drilling mainly uses a small drill in the pit (usually construction is less than 100 meters) to drill holes in or around the circled ore block to check the shape and form of the ore body that has not been mined; at the same time, exploration can also be carried out through construction shafts and sub-middle section along the veins; the construction location and construction plan are mainly arranged according to the morphology of the vein; according to the construction of the above projects, the morphological characteristics of the Jiwo Mine are understood, and then the mining project is arranged for mining. In the process of mining, due to the uncertainty of the Jiwo Mine, it is also necessary to extend or shorten the construction of the Jiwo ore body mining area to reduce the waste of ineffective projects and achieve the maximum economic benefit.
[0020] Extension of the stope: When ore is found at the end of the stope, an economic analysis of the extension construction is conducted based on the ore grade. If it is economically feasible, a 1.2*1.8 extension cutting tunnel is constructed until there is no ore. Shortening of the mining area: When the ore-seeking effect at the end of the mining area is poor, or there is no mineralization at a certain distance from the end, it is necessary to analyze whether the mining area can be shortened based on the previous prospecting projects. If the mineralization of the end cannot be determined based on the previous construction projects, cutting wells or cutting tunnels can be constructed at the end of the mining area to explore the distribution of the non-ore-bearing area and conduct economic analysis.
[0021] At the same time, according to the construction of the previous prospecting project, we can also judge whether to shorten or extend the stope in advance based on the drilling conditions of the previous construction of the Jiwo ore body, so as to recover all the ore bodies in this section; as stated in the manual Figure 2 As shown, the ore is poor in borehole ZK14902, so when the stope construction approaches this area, we will stop mining upwards after there is no ore. We choose to shorten the stope to avoid engineering waste.
[0022] Before prospecting, we collected all the mining data in the Yuelianggou Qiaogou mining area, mainly including: the design of mining sites in the area over the years, the vertical projection map and plane map of the geological catalog of each mining site, the production situation of the mining sites in the area over the years, geological pit exploration, drilling catalog map, the production situation of each vein, the comparison of exploration and mining, scientific research results, etc. After that, we carried out a detailed anatomical study on the existing mineral blocks in Yuelianggou, and determined the geological characteristics, mutual relations and mineralization laws of the established mineral blocks of the existing mineral veins in the area; at the same time, we compared the geological characteristics, mutual relations and mineralization laws of the goaf of the mining blocks, combined with the layout of the surrounding projects of the mining and exploration projects, analyzed the mineralization laws around the mineral blocks, and evaluated the overall mineral block data.
[0023] Project layout and construction: First, conduct a preliminary analysis based on the existing geological blocks that have been delineated, communicate with geological personnel to discuss the reliability of the blocks, and consider whether drilling or pit exploration projects are needed for those with low reliability. After the project blocks reach economic benefits, conduct a preliminary analysis of the mining project layout, and imagine whether the blocks may be extended or shortened. Conduct on-site surveys based on the corresponding relationship between the upper and lower middle sections, block shape, block size, vein thickness, surrounding rock conditions, etc., and report the results of the on-site surveys; at the same time, conduct a safety risk assessment on the site.
[0024] Based on the above survey results, we compared the geological data again, considered the morphological characteristics and mineralization types of different veins, and arranged the mining engineering design according to the company's current "Engineering Design Drawing Specifications" and requirements. When arranging the mining engineering, we must fully consider the characteristics of the ore blocks, the corresponding relationship between the upper and lower middle sections, the surrounding rock conditions, safety factors, etc. Special or typical problems must be considered comprehensively during the design, and solutions must be formulated during the design.
[0025] According to the progress of the mining progress, all kinds of geological cataloging data are collected, compared and analyzed using Micromine and CAD software, and geological, surveying, safety, production and other personnel are convened for geological research. According to the research, the mining veins are reasonably extrapolated or contracted, so as to guide the next step of work and prevent blind construction from causing waste of resources and unnecessary economic losses. After each construction cycle of the mining and exploration project is completed, the research results need to be verified (sampling and testing), and the geological blocks are updated again according to the sampling results. The prospecting, geological cataloging sampling and surveying work designed during the construction process are strictly carried out in accordance with relevant regulations.
[0026] After achieving a basic control level within a certain elevation of the ore vein, a comparative analysis is conducted with the previous mining engineering design plan to see whether additional mining or prospecting projects are needed, and the existing mining and prospecting projects are further optimized to ensure production safety and maximum resource recovery.
[0027] Digital analysis: Collect and digitize all geological data of the mining site, including geological cataloging data implemented at each stage, spatial location of goaf, ore-seeding conditions in ventilation shafts, laboratory analysis data, on-site data on surrounding rock stability, and digital processing of shaft, tunnel and pit engineering data.
[0028] Visual display and mathematical geological statistical analysis are performed through Micromine, ArcMap and CAD software. Compare the application of different exploration lines in the same vein and the same exploration line in different veins in the mining process of inclined thin veins.
[0029] Starting from the characteristics of the same type of ore veins, combined with the original prospecting project, investigate the application of mining and exploration in this type of ore veins. On the basis of achieving basic control of each ore vein block, analyze other ore blocks of the same type of the ore vein, and the ore encounters that may appear during mining; starting from the characteristics of the same exploration line of different ore veins, analyze the geological characteristics, surrounding rock conditions, ore encounters, etc. of the ore veins in the area, and summarize the mining and prospecting projects applicable to different types of ore veins, and establish corresponding combination models, and then compile corresponding mining construction guidance recommendations to establish safe production construction standards for ore deposits in this area.
[0030] Based on exploration before mining, exploration while mining, and exploration and mining combined, we analyze the different morphological characteristics of the ore veins and blocks, and optimize the original traditional mining methods, such as: 1. The upper and lower middle sections are discontinuous in mineralization according to the exploration results. In the original traditional backfill mining method, we can add high chute and secondary middle section supplementary mining projects to maximize the recovery and utilization of resources. 2. In view of the geological characteristics of the study area, the branching and compounding of ore veins are relatively common. In the backfill mining method, extended exploration can be added, and at the same time, the transportation routes can be optimized in combination with the characteristics of the original mining field to improve the resource recovery rate.
[0031] According to the mineralization characteristics of Jiwo Mine and the ore-seeking and mining encounters, this application innovatively proposes to use the concept of "exploration before mining, mining turning into exploration, and combining exploration and mining" to flexibly and reasonably solve technical problems such as losses and depletion; at the same time, it looks for the ore-seeking trend of the ore blocks in the entire ore vein, and reasonably guides the engineering layout of the next stage. This will solve the problem of resource waste in complex ore veins, especially in "Jiwo Mine" and "Vine Branch Complex", and then clarify the new direction of production and mining. Taking advantage of the uncertainty of Jiwo Mine, under the promotion of the exploration and mining project, an effective prospecting or mining project is formed, and the basic characteristics of the original exploration and mining project are combined to further improve the prospecting and mining projects, so that all resources in the project can be recovered, the economic benefits can be maximized, and at the same time, the labor intensity of operators can be reduced.

Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
