摘要
综放开采由于整层开采的特点,可以避免大部分厚煤的损失和局部小地质构造的损失,避免了分层开采工艺难以控制局面。ZFD2600/22/32型高位放顶煤支架,采用新的结构形式,也适合邢台矿的煤层地质条件。
Puts mining because its entire level mining characteristic, may avoid the majority of coal thick loss and the partial small geologic structure loss, hasavoided damaging which the lamination mining craft controls with difficulty loses. The ZFD2600/22/32 top digit puts goes against the coal support, has used the new structural style, is extremely suitable gathers the Xingtai coal bed geology condition.
