到1月14日12时，救援最新发展状况如下：救援现场新增一支43人救援部队，应急救援指挥部共集结救援部队11支、救援人员393名、各类机械设备70余台套参与事端救援，回风井井筒障碍物现已整理至距地上340米；安置4个钻孔商业源码进行施救，完结进尺分别为：1号钻孔（直径311毫米）382米、2号钻孔（直径219毫米）420米、3号钻孔（直径219毫米）397米、4号钻孔（直径711毫米）47米。

现在，现场救援面对较大困难，一是障碍物堆积量大。井筒内的供风、供排水管路、供电和通讯缆线以及梯子间设备掉落，彼此搅在一起，还有矿车等阻塞在井筒中，开始勘探阻塞厚度达7米，清障难度很大。二是人员清障施工难度大。受井筒内施工场所狭隘的约束，现场只能2-3人一起作业，且阻塞物中，金属物和非金属物稠浊在一起，气焊切开有危险、难度大，限制工程进度。三是障物进步难度大。为保证清障过程中的人身安全，依照人与物不能混合进步的准则，提障时操作人员需撤离，导致障碍物进步循环周期长。四是钻孔作业存在困难，因为地质条件杂乱，岩层结构裂隙形成钻孔"卡钻"，施工难度大。钻孔与巷道贯穿后，如涌水量大，易形成井下水位进步，给被困人员安全形成要挟。钻孔深度大、结构多，易呈现误差，完成与巷道精确贯穿有不确定性。

下一步，应急救援指挥部将依照省委省政府要求，不惜全部代价、尽头全部手法，抢抓救援时刻，科学施救，尽最大努力解救被困人员。指挥部将集结更多设备，装置一台用于进步障碍物的绞车，增加液压切开机，集结更多钻机，依据实时检测钻孔涌水量等及时调整施工计划，保证救援作业加快推动。
