[Abstract]:Mineral resources are used by people because of their main resources as energy and industrial raw materials, and the exploitation of mineral resources is becoming more and more extensive. With the development and utilization of mineral resources, people pay more attention to the safety problems in the mining process of underground caverns such as mine roadways. The corresponding evaluation and evaluation of the stability of the surrounding rock of the chamber has gradually formed a discipline for the unstable surrounding rock, which is applied to the underground chamber of each mine roadway. Huanren copper-zinc ore is a typical comprehensive mineral, rich in many non-ferrous metals: copper, silver, lead, iron, zinc, molybdenum. The shaft of Xiangyang mine is a section of shaft for the west relay lifting shaft. The deposit type belongs to skarn type deposit formed by contact zone between intrusive diorite and sedimentary limestone. The proposed hoist room No. 7 of Xiangyangkeng was abolished because of the poor stability of the original rock structure of the working surface during the construction in 1989. In order to reuse, it is necessary to analyze the stability of the hoist chamber. According to the stability of the current situation, appropriate support measures are proposed. First of all, the data collection of the hoist chamber, the investigation, measurement, monitoring, sampling and analysis of the engineering geology on the spot are carried out. According to the actual situation, the domestic and foreign research situation related to the project is collected and studied. Combined with the actual situation of the project, the method of qualitative analysis and quantitative analysis is used to determine the scope of loose ring and the classification of surrounding rock. The range of loose circle is determined by the method of sound measurement of single hole in the field. The range of loosening circle is preliminarily determined by the wave velocity value of the test result, and the range of loosening circle is calculated by the theoretical method combined with the theory of Plain. Synthesizing two kinds of judgment results, the loosening circle range of the winch chamber is finally determined. Based on the test data of physical and mechanical properties of indoor rocks, surrounding rock classification is carried out in combination with relevant codes. The vertical displacement points of the surrounding rock surface of the chamber are monitored, and the relevant data are recorded and arranged. The stability of the hoist chamber of Huanren copper-zinc mine hoist is comprehensively analyzed and evaluated by the loosening zone range, engineering rock mass classification and monitoring data. According to the results of stability analysis, it is suggested that the hoist chamber should be supported by bolting and shotcreting combined with fissure grouting. Through concrete calculation, the form of anchor rod, the length of anchor rod and the way of crack grouting should be determined. The technology and thickness of spray concrete. Because of its relatively low cost, simple construction technology and wide applicability, anchor rod is widely used in underground engineering, slope, foundation pit engineering, bridge and so on, and is widely used in various fields of civil and mining engineering. Anchorage technology at home and abroad has reached more than 600. The methods of qualitative analysis and quantitative analysis are used in all the stages discussed in this paper, and the relatively perfect and advanced theoretical research methods and practical measurement, monitoring and construction techniques are cited at home and abroad. The stability of winch chamber in Huanren copper-zinc mine is analyzed and evaluated objectively and the protection measures are suggested. The method and parameter suggestions are provided for the supporting construction of winch chamber in the future.
