摘要：The principle and test method of drilling strata movement detection is introduced. The failure law of stope drilling strata movement was analyzed and judged by useing the swell character of compresspoed wood when it met upon the water and moves along with surrounding rock. The height of caving zone and subsidence movement failure law of overlying strata and alienation layer could be concluded by combining with the detection experiment of drilling strata movement.The research showed that drilling strata movement detection could make sure the level of destruction of surrounding rock movement and detected the result visualized and met the fine detective requirement with high precision and high resolution, the result was reliable.
