|
摘要
针对陈四楼煤矿采煤工作面采用传统的实中心调斜法及虚中心调斜法期间存在的支护困难、调斜周期长及影响生产接替等问题,运用理论分析和现场实测相结合的方法,分析了传统调斜方法存在的弊端,根据2801综采工作面和巷道的实际情况,提出采用虚—实中心调斜技术,并确定了虚—实中心调斜技术参数及工艺。现场试验表明,采用虚—实中心调斜技术,解决了工作面大幅度调斜期间支护困难、调斜周期长、影响生产接替及液压支架和输送机等设备难于控制的难题。
In allusion to the problems of support difficulty,long adjustment period and influence on production substitution in the course of adopting traditional solid center inclination adjusting method and virtual center inclination adjusting method in the mining face of Chensilou Coal Mine,the disadvantages of traditional inclination adjusting method were analyzed by combining theoretical analysis with field measurement. According to the comprehensive mining face and roadway of 2801 fully-mechanized coal mining face,the disadvantages of traditional inclination adjusting method were analyzed. According to the actual situation of the track,the technique of virtual-real center inclination adjustment was proposed,and the technical parameters and technology of virtual-real center inclination adjustment were determined. Field tests showed that the application of virtual-solid center inclination adjustment technology solved the problems of difficult support during large-scale inclination adjustment,long period of inclination adjustment,difficult control of equipment affecting production substitution,hydraulic support and conveyor.
