平顶山矿务局自1955年建矿以来,相继投产16对矿井,计有矸石山25座,累计排弃煤矸石总量已近3200万吨,占地约1500亩。煤矸石堆放过程中,产生大量粉尘。据测定,1981年矿区降尘量年平均值为72.7t/km~2·月,大气中总浮微粒年日平均浓度为2190~g/m~3。进入80年代后期,煤矸石初步得到综合治理及利用,环境质量有了明显好转。1990年矿区降尘量年平均值为28.78t/km~2·月,大气中总悬浮微粒年日平均浓度为613Pg/m~3。我局在煤矸石治理途径首先是从减少井下产生量入手,其次是地面综合治理两方面措施。
Pingdingshan Mines Bureau since 1955 built, have put into operation 16 pairs of mines, accounting for gangue 25, the total amount of gangue abandoned nearly 32 million tons, covering about 1,500 acres. Gangue dumping process, resulting in a large amount of dust. It is determined that in 1981 the annual average amount of dustfall in the mining area is 72.7t / km ~ 2 · month. The annual average concentration of total aerosol in the atmosphere is 2190 ~ g / m ~ 3. Into the late 1980s, coal gangue initially comprehensive treatment and utilization, environmental quality has been significantly improved. The annual average amount of dustfall in the mining area in 1990 was 28.78t / km ~ 2 · month. The annual average concentration of total suspended particulates in the atmosphere was 613Pg / m ~ 3. My bureau in the gangue management approach is to start with reducing the amount of downhole start, followed by two measures on the comprehensive management of the ground.
