浅析煤矿采空区场地的注浆治理工艺

随着经济快速增长,工程建设用地的紧张程度日益加剧,煤矿采空区的建筑工程发展速度相对较快。然而,由于采空区实际承载能力较弱、地基稳定性差以及易于形变,采空区建筑工程应用受到限制。结合对煤矿采空区地基加固治理的经验,注浆技术因其多重优势被广泛采用,但是整个施工过程复杂烦琐,质量控制难度较大,需要积极掌握技术关键点,采取有效措施保证施工质量。

煤矿采空区场地的注浆治理工艺研究

随着经济高速发展,工程建设用地愈发紧张,煤矿采空区建筑工程发展较为迅速,但因其实际承载力较低、地基不稳定以及易形变等问题,促使难以用于工程建设中。结合对煤矿采空区地基加固治理经验,注浆技术凭借多个优势普遍应用,整个施工流程繁多复杂,质量控制难度把控,需积极掌握相关技术要点,采取强有力的措施保证施工质量可靠性,进一步增强场地实际承载力,吻合建设场地实际需求。

Analysis and research of long-term stability about the gob site in Northern Shaanxi Province

Based on the analysis of the basic characteristics for the gob site in Northern Shaanxi Province and the room and pillar mining way about coal mine, the variety rule of the coal beds below the site was studied by the using of FEM during the process of coal mining. The statuses of the stresses and strains and the varieties of the plastic area were simulated in the whole rock and coal pillars. The characters of stresses and deformation of the gob area of the coalmine were analyzed and evaluated after the site built in weathering. Moreover, the long-term stability of the gob area was predicted. As a result, the deformation of the gob area under the site is not been finished, and there is the danger that the gob site will collapsing as a whole; therefore, relative measures must be taken.
