煤矸石深埋充填采煤塌陷区复垦造地技术研究

Study on reclaimed land reclamation technology of coal gangue in deep filling mining subsidence area

张双楼煤矿本着减少煤矸石占地量、增加耕地有效面积、合理利用土地资源原则,积极探索煤矿塌陷区治理新途径,采取煤矸石深埋充填复垦塌陷地新技术,高质量地复垦了采煤塌陷地151亩。项目施工过程中严格按照以实际地形为基础,结合煤层地质及矿山开采情况,科学合理地编制土地利用现状和规划用地结构平衡表;复垦造出的耕地十分平整,达到耕地平整度标准;耕作层平均厚度在1.2 m左右,符合农作物根系活动所需土壤厚度要求;工程取得了良好的效果,为今后类似塌陷区治理提供了科学借鉴。

According to principle of reducing cover area amount of coal gangue,increasing effective area of arable land, rational utilization land resources, a new approach to manage coal mining subsidence area was active exploration, and new technology for reclamation of subsided land by deep filling with coal gangue was adopt, resulting in coal mining subsidence land 151 acres reclamation of high quality in Zhangshuanglou Coal Mine. In process of project construction, on the basis of actual terrain strictly,combined with coal seam geology and mining situation, land use status and planning land structure balance sheet were drawn up scientifically and rationally, and reclamation cultivated land was very fiat, so as to achieve the leveling standard of tillage,and average thickness of cultivated layer was about 1.2 metres, which accord with soil thickness requirement of crops root activity.This project achieved good results and provided a scientific reference for the similar treatment of subsidence areas in the future.
