Abstract
This invention belongs to the field of coal mine area remediation, specifically disclosing a systematic remediation method for coal mine spontaneous combustion hazard areas. Based on the geological environmental characteristics of the remediation area, a disaster relief and land reclamation model combining "strip-style remediation - silt-retention dam construction - drainage ditch water system dredging - material transportation via roads" is constructed for coal mine spontaneous combustion hazard areas. A "strip-block" remediation process for spontaneous combustion hazard areas is proposed, dividing the remediation strip into segments and implementing tiered interactive remediation. A natural-like soil reconstruction process and a soil improvement method based on risk management are also constructed. This invention can effectively reduce land damage, eliminate spontaneous combustion hazards, increase arable land area, enhance biodiversity, and restore ecosystem functions.
