摘要
矿区构筑物的设计要考虑矿产储量的有限性、二氧化碳浓度偏高和采空区的扩大等因素。本文以平顶山煤业集团的部分构筑物为例,说明了当初没有考虑这些因素而导致日后维护和加固费用的增加,并据此提出了在矿区新建构筑物时的一些建议。
The factors which are limited reserves, high concentration carbon dioxide and enlarge mine gob should be taken into considered when designing the structures in coal area. Taken the part surface structures in Pingdingshan coal group as examples, it shows that the durability problems of concrete structures have not been received enough attention so as to increase maintenance and repair cost. Some improving structures durability.measures for building new structures are presented in the paper.
