Abstract:  With the characteristics of improving the resource recovery ratio, promoting production safety, and protecting the environment, the coordinated paste filling takes an important part of the green coal mining system. However, while it can keep the original state of the environment unchanged, it results in new environmental management costs. Thus, the government should encourage the coal mining enterprises to adopt the coordinated paste filling technology by incentive policy. For this objective, a model is developed for it by treating the relation between the government and coal mining enterprises as principal and agent relation. With this model, the government incentive mechanism is analyzed under different constraints. This is useful for the coal industry to achieve the balance and sustainable development.

Key words: paste filling, principal-agent, incentive mechanism, green coal mining
