当矿井进入收缩阶段进行工业广场煤柱开采时 ,煤矿的咽喉要道——井筒 ,都会产生不同程度的变形、偏斜。如何最大限度地保护井筒 ,对其进行及时、有效的监测 ,以满足正常安全生产的提升需求 ,是所有工作的前提和基础。对于徐州矿务集团有限公司新河煤矿而言 ,由于其丰富的饮用水资源 ,即使煤炭资源完全枯竭 ,也应保持井筒完好。本文就新河煤矿主井偏斜的原因进行了初步分析 ,并对以后如何进行监控提出了一些思路 ,以期对类似的衰老矿井起到一定的借鉴作用。
When the coal mine into the contraction phase of industrial square pillar mining, the coal mine’s throat - wellbore, will have varying degrees of deformation, deflection. How to maximize the protection of the wellbore, to conduct timely and effective monitoring to meet the upgrading needs of normal safety production is the precondition and foundation of all work. For Xinhe Coal Mine of Xuzhou Mining Group Co., Ltd., due to its abundant drinking water resources, the wellbore should be kept intact even if the coal resources are completely depleted. This paper makes a preliminary analysis of the reason of main shaft deviation in Xinhe Coal Mine and puts forward some ideas on how to carry out monitoring in the future so as to provide reference for similar aging mines.
