井下巷道贯通测量方案 井下贯通测量方案 摘要：巷道贯通是指采用两个或多个相向或同向的掘进工作面分段掘进巷道，使其按设计要求在预定地点彼此结合。在煤矿开采过程中,贯通测量是矿井建设发展的重要一环。由于贯通测量工作涉及地面和井下,不但要为矿山生产建设服务,也要为安全生产提供信息,以供管理者做出安全生产决策。贯通测量的任何疏忽都会影响生产,甚至可能导致事故的发生。因此，贯通测量是一项非常重要的测量工作，测量人员所肩负的责任是十分重大的。如果因为贯通测量过程中发生错误而导致巷道未能正确贯通，或贯通后结合处的偏差值超限，都将影响巷道质量，甚至造成巷道报废，人员伤亡等严重后果，在经济和时间上给国家造成重大的损失。 关键词：巷道； 贯通； 测量 井下巷道贯通测量方案 The mine through Measurement Programme Abstract：The roadway through refers to the use of two or more opposite or segmented with the heading face to the roadway, according to the design requirements combined with each other at the predetermined location. In the coal mining process, through measurement is an important part of the mine construction and development. Through measurements involving ground and underground, not only for mine production and construction services, but also provide information for the safe production, for managers to make safety production decisions. Through the measurement of any negligence will affect production, and may even lead to accidents. Therefore, through measurement is a very important survey work, the responsibilities surveyors is very significant. If being versed in measurement error occurs during which led to the tunnel failed to correctly through, or through joint deviation limit, will affect the roadway quality, even cause roadway scrapped, injuries and other serious consequences, in economy and the time to the national cause significant loss.
