摘要:【中文】本发明涉及采煤方法技术领域,尤其是一种用于控制地表变形的径向采煤方法,包括以下步骤:S1、选择合适的开采区域;S2、建立主井,主井设置在拟开采区域的中心处;S3、在主井的周围圆形区域设置煤仓,并环绕煤仓设有圆形的内径支护;S4、切眼施工:设置多个切眼,多个切眼为先后施工或者同时施工,切眼设置在以煤仓为圆心的圆形的半径上,所述切眼的一端与煤仓连通;S5、设置支护壁:切眼施工完成后沿着切眼的径向布置好采煤设备和支护及喷浆系统;S6、采煤作业。本发明能够对资源进行合理利用,减少浪费,且能够控制地表变形。 【EN】The invention relates to the technical field of coal mining methods, in particular to a radial coal mining method for controlling surface deformation, which comprises the following steps: s1, selecting a proper mining area; s2, establishing a main well, wherein the main well is arranged in the center of the area to be mined; s3, arranging coal bunkers in the circular area around the main well, and arranging a circular inner diameter support around the coal bunkers; s4, hole cutting construction: arranging a plurality of cutting holes, wherein the plurality of cutting holes are constructed sequentially or simultaneously, the cutting holes are arranged on the radius of a circle with the coal bunker as the center of the circle, and one end of each cutting hole is communicated with the coal bunker; s5, arranging a supporting wall: after the hole cutting construction is finished, coal mining equipment and a supporting and guniting system are arranged along the radial direction of the hole cutting; and S6, coal mining operation. The invention can reasonably utilize resources, reduce waste and control the deformation of the earth surface.
