从盖依采选联合企业开工的初期,全体工作人员就对矿床的矿石储量综合利用给予极大重视,在联合企业,制定了地下资源保护和矿物原料利用的特别计划。盖依矿床拥有足够数量的建筑材料,诸如辉绿岩玢岩、砂-砾混合物、砂和粘土。在剥离和开采矿床时,辉绿岩-玢岩被采出并存入单独的废石场。目前,已堆存了约1000万立方米建筑材料,获得了160万立方米建筑碎石。用房式阶段采矿法和采空区充填法(固
From the very beginning of the operation of the coal-mining joint venture, the entire staff gave great importance to the comprehensive utilization of ore reserves in the deposit. In the joint ventures, special plans were formulated for the protection of underground resources and the utilization of mineral raw materials. The Gai deposit contains a sufficient amount of building materials such as diabase pluton, sand-gravel mixture, sand and clay. Diabase-porphyrite is extracted and deposited in a separate waste field during the stripping and mining of the deposit. At present, about 10 million cubic meters of building materials have been piled up and 1.6 million cubic meters of building rubble have been obtained.
