Description

条带充填整体回采采煤方法 Strip - filling stoping mining method overall

技术领域 FIELD

[0001] 本发明涉及一种煤层开采的回采采煤方法,特别是一种适用于“三下”煤层开采的条带充填整体回采采煤方法,可实现安全回采,并可以达到与现有综合机械化开采同样的煤炭回收率,同时可将煤层上覆岩层和地表的沉降控制在允许的极小范围内,保证地表建筑和附着物的安全。 [0001] The present invention relates to a method of mining coal seam mining, particularly suitable for use in conventional synthesis from "three" in the coal seam strip mining method of filling the entire recovery, mining enables safe, and can be achieved with mechanized mining coal recovery the same, while the seam overburden and surface subsidence can be controlled within the allowable range of the minimum, and ensure the safety of the building surface deposit. 属于煤炭开采方法领域。 The method belongs to the field of coal mining.

背景技术 Background technique

[0002] 目前我国对积压在村庄和重要建筑、路桥设施和湖泊等水体地下(通常称“三下”)的煤层进行开采的采煤方法比较有限,如果不采取适当措施,贸然对此类煤层进行开采,煤层上覆岩层的塌落和断裂就会造成地表的严重沉降和移动,从而导致地面的村庄和重要建筑、路桥设施和湖泊水体等遭到破坏;如果是在水下,更可能导致煤层透水,井下发生严重安全事故,地表的水体资源也会受到严重破坏。 [0002] At present, China backlog in water underground villages and important buildings, road and bridge facilities and lakes (commonly referred to as "three times") method of extracting coal seam will be more limited, if appropriate measures are not taken hastily on such coal mining, coal seam overburden collapse and fracture can cause severe ground subsidence and movement, leading to the ground villages and important buildings, roads, bridges and other facilities and lake water damaged; if it is underwater, is more likely to lead to permeable coal seams underground serious security incidents, surface water resources will be seriously damaged.

[0003] 已知的开采方法有三类:其一是房柱式开采,它是将被开采煤体开采成比较规则的房柱状,通过留设的矿房间柱、区段隔离煤柱等支撑上覆岩层重量,而达到控制顶板岩层破坏与垮落,减小采动对地面建(构)筑物影响的目的。 [0003] There are three known extraction methods: one is the room and pillar mining, it is to be mined coal body opening to compare regular columnar room by room Pillar of ore, coal pillar like insulating support sections weight of overburden, and to control collapse and destruction roof strata, to reduce the impact object mining building was built on the ground (infrastructure). 房柱式开采的煤炭资源回收率往往不及40%,而且支护手段欠缺,易发生冒顶事故,在非特殊条件下是被禁止采用的方法。 Coal resource recovery room and pillar mining is often less than 40%, and the lack of means of support, roof fall accident prone, methods used in a non-specific conditions is prohibited. 其二是充填开采,它是用矸石、黄土、水砂等材料充填采空区,阻止顶板岩层冒落破坏的发展与扩大,最终达到减缓地表沉陷,保护地面建(构)筑物的目的。 The other is filled with mining, it is waste rock, loess, sand water and other materials filling mined-out area to prevent the destruction of caving roof strata development and expansion, ultimately slowing surface subsidence, ground protection purpose built (structure) of. 如专利公开号为CN1936271A的“煤矿矸石充填无煤柱开采工作面采空区的方法”,公开了一种将煤矿矸石通过运输机和皮带等机械充填到采空区的办法。 Patent Publication No. "free coal refuse backfilling goaf pillar coal mine face approach" CN1936271A, there is disclosed an approach to the coal and gangue through conveyor belt or the like is filled into mechanical goaf. 这类方法受材料、设备、工艺的局限,充填物无法密实的充满采空区,而且该方法在采空区作业的设备和人员都无法在安全有效的支护条件下作业,所以在防止地表沉陷上仍有较大局限。 Such methods are limited by the material, equipment, process, not dense filling goaf filled, and the process equipment and personnel in the goaf job can not work in a safe and effective support conditions, the preventing surface the subsidence is still a large limitations. 其三是条带开采并附以矸石充填的方式,它是将被开采的煤层划分成规则的条带状,采一条,留一条,通过减小开采块段内煤层绝对开采面积,而达到减小地表移动和变形,保护地面建(构)筑物的目的。 The third is to attach strip mining waste filling manner, it is divided strip mined seams in a regular, a mining, a left, by reducing the absolute mining Coal mining segment block area, and achieve reduction small movement and deformation of the surface and protect the floor construction (structure) of the. 如专利公开号为CN1483921A的“洞穴填充采煤方法”、专利公开号为CN1952349A的“利用矸石置换村庄下压煤的开采方法”、专利公开号为CN1963149A的“建筑物下矸石置换条带煤柱的开采方法” 等,公布的方法就属于此类。 Patent Publication No. CN1483921A the "cave fill mining method", Patent Publication No. CN1952349A the "waste - Method of Coal Mining substituted lower village", Patent Publication No. CN1963149A "next building gangue replacement strips Pillar mining methods "and other published methods belong to such. 这类方法的煤炭回收率低,只有大约30% _50%,虽然附以矸石回填的办法,对减缓地面沉降有一定的效果,但是从资源回收率极低和开采成本增加很多、安全性差等方面考虑就有些得不偿失了。 Low coal recovery rate of these methods, only about 30% _50%, although attached approach to waste rock backfill, to slow down the ground have a certain effect settlement, but the increase in the recovery rate is very low and a lot of resources from mining costs, poor security aspects some consider harm than good. 还有如专利公开号为CN1410655A的“建筑物或构筑物下压煤大条带协调式全部开采方法”中,公布的是一种先进行跳采,再将跳采所留的煤层区段同时进行快速强采的方法,它也是条带开采的一种,虽然这种方法的回采率有了很大提高,但是地表沉陷的不均勻性仍然较大,而且关键的后期强采阶段在不同地区和煤层条件下的地表移动变形是很难得到保证的,因此,能否达到预期的沉降效果的影响因素较多,存在较大风险。 There Patent Publication No. CN1410655A as the "pressure of coal under buildings or structures coordinated all the big bands mining methods", to be published in a skip - mining, coal mining sections and then jump to the left, while fast strong mining methods, it also strips for recovering, although the recovery rate of this method has been greatly improved, but the unevenness of surface subsidence is still large, but the key late stages of strong mining and coal seams in different regions ground movement and deformation under conditions it is difficult to be guaranteed, therefore, many factors can achieve the desired effect of the settlement, there is a big risk.

[0004] 综上所述,国内、外目前尚未见对“三下”煤层进行高回收率、高产、高效的综合机械化的理想开采方法的相应报导。 [0004] In summary, domestic and foreign has yet to see on the "three times" seam accordingly reported high recoveries, mining methods ideal for high-yield, efficient integrated mechanization. 发明内容 SUMMARY
