耕地是粮食安全的基础，煤炭是能源安全的保障。我国煤炭和耕地资源分布重合的煤粮复合区面积约占耕地总面积的42.7%，煤炭开采与耕地保护之间的矛盾十分突出。如何实现煤矿开采与耕地保护协同发展是我国煤粮复合区亟待解决的瓶颈难题。从平原煤粮复合区采动耕地损毁机理、采动耕地破坏程度评价、开采沉陷控制技术等3个方面分析了煤矿开采和耕地保护协同发展的研究现状与存在问题。在此基础上结合耕地保护面积大、变形耐忍度高等特点，提出了一种面向煤矿开采和耕地保护协同发展的源头控制与修复治理有机结合的绿色开采区域性岩层及地表变形控制技术途径，建立了相应的地表变形预测及控制设计方法，并指出了平原煤粮复合区煤矿开采和耕地保护协同发展的重点研究方向：平原煤粮复合区耕地采损驱动机制、采煤沉陷耕地防护阈值体系、面向耕地保护的煤矿绿色开采区域沉陷协调控制理论与方法，以期推动煤粮主产复合区煤矿绿色开采与耕地保护协同发展。

Cultivated land is the foundation of food security, while coal guarantees the security of the energy. The coal-cropland overlapped area accounts for approximate 42.7% of the total cultivated land area in China, making it become a prominent contradiction between the extensive mining and cultivated land protection. How to realize the coordinated development of the coal mining and the cultivated land protection is an urgent problem in coal-cropland overlapped areas. This paper analyzes the research status and existing issues of the coordinated development between mining and cultivated land protection from the following three aspects: the damage mechanism of subsidence land in plain coal-cropland overlapped areas, the damage degree evaluation of subsidence land induced by mining, the control technology for the mining subsidence. Then, considering the characteristics of the cultivated land, such as the extensive protection-needed area and the high deformation tolerance, a new technical approach of controlling regional rock strata and surface deformation in green mining is proposed by combining source control and restoration. The corresponding prediction and control design methods of surface deformation are established. Additionally, the key research directions for the coordination of coal mining and cultivated land protection in the plain coal-cropland overlapped areas are pointed out, including the driving mechanism of cultivated land damage induced by mining in the plain area, protection thresholds for the quality of the cultivated land in subsidence areas, theories and methods of the subsidence coordinated control of the green mining facing the cultivated land protection. The main objective of this paper is to promote the coordinated development of the green mining and the cultivated land protection in the plain coal-cropland overlapped areas.
