How ever, it alr eady 3 2 has 7 . 52 10 hm subsidence area caused by coal mining, which is 37. 6 percent of the total coal field ar ea. T he coal resources is near ly exhausted, and the ecolog ical environment is destro yed heav ily. T he land resour ces is becoming a restriction of social economy development . T he recultivation and administration of subsidence area has no time to delay, especially the engineering measure of recultivation and its utilization direction should be paid mor e attention to.
