砂岩是生产玻璃的主要原料,为改变落后局面,缓解供需矛盾,国家建材局委托苏州非金属矿山设计院,协助沈阳玻璃厂编制扩建本溪小平顶山砂岩矿设计任务书。5月28日已对扩建工程进行了可行性研究。
Sandstone is the main raw material for glass production. In order to change the backward situation and ease the contradiction between supply and demand, the National Building Materials Bureau commissioned the Suzhou Non-metallic Mine Design Institute to assist the Shenyang Glass Plant in the preparation and expansion of the Benxi Xiaopingdingshan sandstone mine design task book. On May 28, a feasibility study of the expansion project was conducted.
