Example Embodiment
[0027] Embodiment:
[0028] (1) First step, determine the monitoring of the roadway area. A iron ore -230m level is the first mid-section, which is extremely critical for safety production, so the typical section is selected in the pulse roadway along the pulseway. A total of 5 areas, about 4.8 m × 3.85 m, and the ground pressure monitoring is mainly based on stress, deformation monitoring, and the ground pressure monitoring equipment uses anchor stress meter and multi-point displacement.
[0029] (2) The second step, performing pressure monitoring and data analysis of the lane road. The lane-lane pressure monitoring is an anchor or anchor ratio, along the roadway to arrange a group, continuous observation of the pressure load of the roadway surrounding rock, and systematically analyzed the results of the monitoring data, and obtained the roadway Rock pressure load change process curve.
[0030] Each set of anchors include: 1 6m deep diamond as a monitoring point in two bodies and...

The invention relates to an underground mine soft rock roadway ground pressure safety early warning monitoring method, and belongs to the technical field of heavy rail ultrasonic flaw detection methods. According to the technical scheme, the method comprises the steps that firstly, a soft rock roadway which is extremely critical to safety production is selected as a key monitoring area, ground pressure monitoring equipment is installed, and ground pressure monitoring is mainly stress and deformation monitoring; then roadway surrounding rock pressure monitoring and data analysis are conducted, and roadway surrounding rock deformation monitoring and data analysis are conducted; finally, all-dimensional remote dynamic monitoring is conducted. The method has the advantages that soft rock roadway surrounding rock stress monitoring and surrounding rock deformation monitoring are closely linked together for comprehensive ground pressure monitoring, continuous collection, online identification, intelligent analysis and disaster early warning of underground mine soft rock roadway ground pressure dynamic information are achieved, ground pressure disaster control measures are taken in time according to the monitoring condition, and the mine safety production major disaster early warning capacity is improved; the effect of capturing roadway surrounding rock pressure and deformation rules is remarkable, field organization and implementation are facilitated, the method is economical and feasible, and reference can be provided for design of a broken stope bottom structure and a rock drilling chamber deformation monitoring system.
Description
technical field [0001] The invention relates to an early warning monitoring method for ground pressure safety in soft rock roadways of underground mines, and belongs to the technical field of ultrasonic flaw detection methods for heavy rails. Background technique [0002] The appearance of ground pressure is the deformation, cracking, breaking, chipping, collapse and roof fall of the surrounding rock mass and support structure caused by the formation pressure acting on the mining tunnel and stope. It is one of the main reasons for the difficulty of mining underground deposits. . Many domestic mines suffer from this, such as Zhangjiawa Iron Mine, Shouyun Iron Mine, Xiaoguanzhuang Iron Mine, Xishimen Iron Mine, Yushiwa Iron Mine, Chengchao Iron Mine, Jinshandian Iron Mine, Maoyuan Iron Mine, Jinchuan Nickel Mine A large number of mines, such as Tonghua Jien Nickel Mine, Fanshan Phosphate Mine, Kaiyang Phosphate Mine, Jiaojia Gold Mine, Jinfeng Gold Mine, Fengshan Copper Mine,...
