遵照伟大领袖毛主席关于“以农业为基础、工业为主导”的教导,我矿将排土场进行了调整与改造,做到了不占良田,少压耕地或缓征耕地。自1965年至今,剥离了大量的废石,均排卸在原排土场的上部,未占用一分农田,节省农田2567亩,提高了排弃生产能力40%左右,缩短了运距,提高了运输效率20%;予计在1974年底基本完成排土场改造,为今后矿山生产创造了有利的条件。(一)排土场的调整与改造如图1所示,我矿原设计的排土场,在东露天采场有团山和象鼻山南部二个汽车排土场,在它的西南部设有大理岩和闪长岩两个机车排土场;在西露天采场的北部和西南部共有4个汽车排土场。自建矿以来,在不影响采场安全和边坡稳定的原则下,利用地形,结合我矿生产的实际情况,采用分散与集中相结合的排土方法, In accordance with the teachings of Chairman Mao, the great leader, on “taking agriculture as the foundation and industry as the leading factor”, the mine has adjusted and renovated the dump so that it will occupy less land, reduce the pressure on cultivated land or ease the acquisition of cultivated land. Since 1965, a large amount of waste rock has been stripped off and discharged to the upper part of the original dumping site. There is no occupation of one farmland, saving 2567 mu of farmland and raising the disposal capacity by about 40%, shortening the distance and improving Transportation efficiency of 20%; it is estimated that basically completing the reconstruction of the dump at the end of 1974, creating favorable conditions for future mine production. (I) Dumping Site Adjustment and Remodeling As shown in Figure 1, the original dump site designed by our mine has two vehicle dumps in Mission Hills and Cheung Pei Shan in the east open pit. In its southwest There are two locomotive dumps of marble and diorite; there are a total of four car dumps in the north and southwest of the western open pit. Since the construction of the mine, under the principle of not affecting the safety of stope and the stability of the slope, using the topography, combined with the actual situation of mine production, using the method of combining drainage with concentration,
