Abstract：Shengdong Diggings is located in Maowusu Sandland area,the water resource of which is very short and the environment is degrated seriously.According to the problems such as soil erosion and desertification,water resource protection and environment restoration etc,Shengdong Diggings,as the biggest public colliery in china,has used comprehensive technological system to coal resource development,vegetation restoration,heat energy use of coal gangue and so on.The system is appropriate in ecological,economical,and social benefits.The economic benefit of coal resource development increased continually.Meanwhile,the vegetation coverage was improved from 3%-11% to 59.4% and the average erosion modulus was decreased about from 10 000 t/(km<sup>2</sup>·a) to 1 500 t/(km<sup>2</sup>·a).Therefore desertification in diggings area had been controlled distinctly. The annual repeated amount of mines' water is 4 960 000 t/a;coal gangue product rate of a ton coal was reduced from 20% to 5%.The consumed amount of coal gangue for electric power reached 8 million ton every year,and the electric power generated 43.6 hundreds million kW·h.
