近来,在主要煤田区新建的矿井的地面建筑物和结构物,均系按把生产厂房布置在大型的同体建筑物中的定型设计建造。这些建筑物是以统一模数制为基础进行组合的,其主要尺寸的确定和采用是为了使装配式结构(特别是钢筋混凝土结构)规格的划一。照例,矿井地面所有建筑物的柱间距均为6公尺,跨度是3公尺的倍数,及楼层高度是0.6公尺的 Recently, ground buildings and structures in newly built mines in major coalfields have been constructed in a stereotyped design that houses production plants in large condominiums. These buildings are combined on the basis of the unified modular system. The main dimensions are determined and adopted in order to standardize the specifications of fabricated structures (especially reinforced concrete structures). As usual, the column spacing of all buildings on the mine floor is 6 meters, the span is a multiple of 3 meters, and the floor height is 0.6 meters.
