肥城煤矿区位于肥城市北部的康汇平原高产农业区,是山东省煤炭生产基地之一。矿区东西长23km,南北宽7.8km,储煤面积为93.53km~2,总储煤量11亿t。自1958年以来,13处煤矿先后投产,矿区地面逐年塌陷,截至1991年底止,塌陷地面积已达4710.6hm~2,其中长年积水面积987.8hm~2,季节性积水面积971.1hm~2。矿区新的水土流失非常严重,年均土壤侵蚀模数为5199.7t/km~2。昔日的高产粮田变为积水、低湿的倾耕地,由于土地废弃不能利用,每年少收粮食1550万kg。肥城市土地后备资源不足,人口逐年增多,塌陷地的开发利用显得尤为重要。为此,我们
Feicheng Coal Mine is located in the northern part of Feicheng Plain High-yield agriculture area, is one of the coal production base in Shandong Province. The ore area is 23km long from east to west and 7.8km wide from north to south with a coal storage area of 93.53km ~ 2 and a total coal reserve of 1.1 billion t. Since 1958, 13 coal mines have successively been put into operation and the ground surface of the mining area has been subsided year by year. As of the end of 1991, the subsidence area has reached 4710.6 hm ~ 2, of which 987.8 hm ~ 2 for long years and 971.1 hm ~ 2. The new soil erosion in the mining area is very serious with an average annual soil erosion modulus of 5199.7t / km ~ 2. In the past, the high-yielding grain-crops in the past turned into waterlogged and low-wet tillage fields. Since the land can not be used for disposal, the annual output of grain is less than 15.5 million kg. Feicheng land reserve resources is insufficient, the population increased year by year, the development and utilization of subsidence is particularly important. For this, we
