根据邵新煤矿的地质采矿条件,按照概率积分法和《建筑物、水体、铁路及主要井巷煤柱留设与压煤开采规程》预测矿山开采造成的地表移动变形和导水裂隙带高度。预测结果表明,邵新煤矿西北区多煤层重复开采后斜率i=1.273～26.498 mm/m,曲率k=0.006×10~(-3)～1.081×10请下载后查看，本文暂不支持在线获取查看简介。(-3)m~(-1),水平变形ε=0.729～15.183mm/m;东南区多煤层重复开采后斜率i=1.273～22.473 mm/m,曲率k=0.006×10~(-3)～1,011×10~(-3)m~(-1),水平变形ε=0.729～12.878 mm/m;冒落带高度为3.118～3 274 m,导水裂隙带高度为18.76～20.91 m。受深部煤层采动的影响,矿山开采后地面建筑物破坏等级为Ⅰ～Ⅳ级,结构处理为简单维修～大修;受近距离煤层采动的影响,K_(21)煤层露头线2侧附近居民建筑破坏等级可能达到Ⅳ级,结构处理为大修。导水裂隙带最高达到K_(21)煤层以上19.27 m,花石水库出露地层为侏罗系中统下沙溪庙组(J_2x),矿井开采不会导致水库漏失,但会对须家河组第2段T-3xj~2、第4段T_3xj~4裂隙含水层地下水产生疏降作用。煤矿开采会导致邵新煤矿采空区内煤层浅部坡耕地出现细小地裂缝,但不会改变农业生产的基本格局。
According to the geological mining conditions in Shaoxing Coal Mine, the surface movement deformation and the height of water-conducting fractured zone caused by mine exploitation are predicted according to the method of probability integration and the Code of Coal Pillar Settlements and Pressure Coal Mining in Buildings, Waterways, Railways and Main Mine Roadways. The prediction results show that the slopes i = 1.273 ~ 26.498 mm / m and the curvature k = 0.006 × 10 ~ (-3) ~ 1.081 × 10 after repeated mining in the northwestern area of Shaoxing Coal Mine. Please do not hesitate to get online View profile. (-3) m ~ (-1), horizontal deformation ε = 0.729 ~ 15.183mm / m; the slope of multiple coal seams in the southeast area is i = 1.273 ~ 22.473 mm / m and curvature k = 0.006 × 10 ~ (-3) ~ 1,011 × 10 ~ (-3) m ~ (-1), horizontal deformation ε = 0.729 ~ 12.878 mm / m, the height of caving zone was 3.118 ~ 3 274 m, and the height of water guiding fractured zone was 18.76 ~ 20.91 m. Affected by the mining in deep coal seams, the damage of ground buildings after mining is from grade Ⅰ to Ⅳ, and the structure is treated as a simple maintenance-overhaul. Affected by the mining with close intervals, residents near the side of outcrop line K_ (21) The level of building damage may reach Grade IV, and the structure is treated as overhaul. The water-bearing fractured zone reaches up to 19.27 m above the K 21 coal seam, and the outcrop formation of the Mishi Reservoir is JXX of the Middle Jurassic system. Mining in the mine will not result in reservoir loss but will affect the Xujiahe Formation 2-stage T-3xj ~ 2, paragraph 4 T_3xj ~ 4 fissured aquifer groundwater generation and drainage effect. Coal mining will lead to minor cracks in the shallow sloping arable land in the coal mined area in Shaoxin coal mine, but will not change the basic pattern of agricultural production.
