Some thoughts on green development strategy of coal industry：from aspects of ecological restoration

The coal industry is facing unprecedented environmental pressure.The construction of ecological civilization and green development have become the national strategy， therefore， the coal industry， as the main energy resource in China， must take the road of green and sustainable development inevitably.This paper expounds the necessity and urgency of the green development of coal industry from the aspects of the inevitability and severity of the impact of coal mining on the environment and the urgency of the national green development strategy.Some thoughts on the green development strategy of coal industry was proposed， which are fulfilling the obligation of ecological restoration， green mining， full life cycle ecological restoration， coordinated development of mining and environmental protection， concurrent mining and reclamation， differential treatment， clean recycling and innovative development.To fulfill the obligation of ecological restoration is the premise of green mine construction； the ecological restoration of coal resources development in the whole life cycle through the four stages of geological exploration， mine design， mine production and mine closure is the basis for the restoration of the overall protection and systematic restoration； the management strategy of differentiation of reclamation treatment and concurrent mining reclamation is the guarantee of efficient construction of green mines； and clean utilization and innovative development are the driving force of green mine construction and sustainable development.We proposed that coal enterprises should take the initiative to implement ecological restoration and green mining as the two core indicators to measure whether a mine is a green mine.The core strategy of green development is full life cycle ecological restoration， concurrent mining and reclamation and differential governance， and the core idea of green development is collaborative development and innovative development.It is an urgent problem to increase the content of ecological restoration and green mining in mine design and planning.
