Description

煤与瓦斯突出矿井110工法开采的立体通风方法及系统
本申请要求于2020年4月30日提交中国国家知识产权局专利局、申请号为202010367085.2、发明创造名称为“煤与瓦斯突出矿井110工法开采的立体通风方法及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及矿井通风技术领域，尤其涉及一种适用于煤与瓦斯突出矿井110工法开采的立体通风方法及通风系统。
背景技术
目前，在进行煤炭开采过程中，通常采用如图1所示的121工法，即一个工作面需先挖掘两个巷道，并且留一个煤柱作为支撑。具体说来，每个工作面包括上顺槽、下顺槽和开采作业面。目前的这种结构中，需要留设煤柱，造成资源的大量浪费。而且，每个工作面都需要挖掘两个巷道，工作效率低。
切顶卸压无煤柱自成巷“110”工法是一种先进的无煤柱开采技术，是保持我国煤炭资源可持续发展的关键技术之一，亦是解决瓦斯与动力灾害、提高煤炭回收率、降低巷道掘进率、实现科学采矿的重要保障。“110”工法无煤柱开采技术是指通过对回采巷道进行补强支护后，在巷道将要形成采空区侧进行定向预裂爆破，将顶板按照设计位置进行切缝，切缝结束后随着工作面煤层的回采，在矿山压力作用下，采空区顶板沿着预裂切缝垮落形成巷帮，利用原巷道部分空间和支护自动形成新巷道，作为下一工作面的回采巷道的技术。无煤柱自成巷开采技术通过采用预裂爆破、恒阻锚索补强支护、架后挡矸等技术手段，减弱了采场顶板作用于巷道的压力，不留区段煤柱提高了资源回收率，同时每个回采工作面少掘进一条回采巷道，降低了煤矿万吨掘进率。尤其在煤与瓦斯突出煤矿中，少掘进一条回采巷道可减少约50％的瓦斯 治理工作量和时间，解决煤与瓦斯突出煤矿采掘接替困难的问题。
综合现有技术可知，需要对现存大量的传统“121”工法向“110”工法切顶留巷进行转换，但是在“110”工法形成的切顶留巷段没有回风通道，不能形成完善回风系统，给煤矿生产带来诸多安全隐患。因此在“121”工法向“110”工法进行转换的初期，在未形成Y型通风或W型通风之前使用“110”工法切顶留巷时，留巷段不能形成完善的回风系统，会导致留巷段无法进行监测围岩变化、留巷段有毒有害气体积聚、无法在留巷段打钻进行瓦斯治理等问题，还会增加煤矿开采的经济成本。

如图1所示，给出了现有技术中煤与瓦斯突出矿井121工法开采过程中的通风系统示意图。如图所示，每个工作面对应设置有工作面运输顺槽4、工作面轨道顺槽5和采煤作业面3，各工作面的工作面运输顺槽4连通进风大巷1，各工作面的工作面轨道顺槽5连通回风大巷2，另外还设置有用于瓦斯抽采的瓦斯抽采进风巷6和瓦斯抽采回风巷7，瓦斯抽采进风巷6和瓦斯抽采回风巷7通过短巷10连通后形成通风回路。目前的这种结构中，需要留设煤柱，造成资源的大量浪费。而且，每个工作面都需要掘进两条顺槽，两条瓦斯抽采巷，造成矿井严重采掘失调。
为了充分利用先进的开采工艺，大量矿井由121工法过渡转换至110工法，图1所示的矿井通过110工法开采后，工作面轨道顺槽5位于采空区的部分会形成第一切顶留巷段，工作面运输顺槽4位于采空区的部分会形成第二切顶留巷段，未形成Y型通风或W型通风之前使用“110”工法切顶留巷时，留巷段不能形成完善回风系统，该施工方法存在如下问题：未形成完善的通风系统导致人员无法进入，不能对巷道围岩变化进行实时监测，掌握不了围岩变化数据，影响对留巷段围岩变化规律的研究及推广应用；留巷段密闭以后，采空区和临近煤层的有毒有害气体不断涌入，在复用留巷段的过程中容易导致人员中毒和引发瓦斯爆炸等安全事故；留巷段密闭以后，无法在留巷段施工下个回采工作面瓦斯抽采钻孔和临近煤层瓦斯治理工程，增加瓦斯治理工程时间，导致采掘失调，影响煤矿生产进度；增加了留巷经济成本，降低了煤矿企业经济效益。
图1所示的通风系统中的通风线路为：
(1)新鲜风流→进风大巷1→工作面运输顺槽4→采煤作业面3→工作面轨道顺槽5→回风大巷2。
(2)新鲜风流→进风大巷1→瓦斯抽采进风巷6→短巷10→瓦斯抽采回风巷7→回风大巷2。
为了解决上面的技术问题，本申请实施例提供了一种煤与瓦斯突出矿井110工法开采的立体通风方法，适用于采煤区，所述采煤区的通风系统包括进风大巷1、回风大巷2、采煤作业面3、工作面运输顺槽4、工作面轨道顺槽5、瓦斯抽采进风巷6和瓦斯抽采回风巷7，其中所述立体通风方法包括以下步骤：
在工作面回采前，施工第一工艺巷8或第二工艺巷9，所述第一工艺巷8的一端连接所述工作面轨道顺槽5远离所述回风大巷2的一端，所述第一工艺巷8的另一端连接所述瓦斯抽采回风巷7，所述第二工艺巷9的一端连接所述工作面运输顺槽4远离所述进风大巷1的一端，所述第二工艺巷9的另一端连接所述瓦斯抽采进风巷6；
在所述工作面回采过程中，所述工作面轨道顺槽5位于采空区的部分形成第一切顶留巷段11或所述工作面运输顺槽4位于采空区的部分形成第二切顶留巷段12，使得所述第一切顶留巷段11的进风通过所述第一工艺巷8进入所述瓦斯抽采回风巷7形成回风，或使得所述第二切顶留巷段12的进风通过所述第二工艺巷9进入所述瓦斯抽采进风巷6形成回风。

优选的，图2-图4中所示的第一调节风门14、第二调节风门15、第三调节风门16和第四调节风门17均为双向调节风门，可以采用电子风门实现远程控制。

(1)加快留巷工程进度。形成了完善的通风系统，减少了工人劳动强度；回采结束后直接复用，不在需要拆除密闭，加快留巷工程进度。
(2)留巷段可实时监测。留巷段取消密闭后，在巷道内安装围岩变化监测仪器，人员可随时进出，对巷道围岩变化进行实时监测，掌握围岩变化数据，便于对留巷段围岩变化规律的研究及推广应用。
(3)留巷段有毒有害气体不再积聚。留巷段取消密闭后，采空区和临近煤层的有毒有害气体随着风流排出地面，不在积聚，减少了人员中毒和瓦斯爆炸等安全事故。
(4)留巷段可打钻进行瓦斯治理。留巷段取消密闭后，回采同时可统筹安排留巷段施工下个回采工作面瓦斯抽采钻孔和临近煤层瓦斯治理工程，减少瓦斯治理工程时间，解决矿井采掘接替困难的问题。
(5)降低煤矿经济成本。留巷段取消密闭后，减少留巷经济成本，提高煤矿企业经济效益。
