Abstract

With the increase of mining depth, dynamic disaster is more severe, which is a serious threat to the safety of miners. Because of complex mine geological structure, and relatively junior safety facilities, tunnel collapse and other dynamic disasters are easily induced, which brought great difficulty to the rescue work. During the rescue, the original mine monitoring and communication device of mine, and regular ground communication and detection technology cannot work properly. Therefore, the location of the trapped miners and the real situation of the disaster area would not be grasped by rescue workers. Therefore, several key technologies were adopted to develop the drilling hole detection device for multiple information after mine disaster, such as the Symmetric Digital Subscriber Line (SDSL) cable transmission technology, the integrated technology that includes of the dual-stream technology, hierarchical synchronization method and timestamp synchronization method, a multimedia relay remote transmission technique combining wireless dual band Mesh network and SDSL cable transmission. Based on technologies above, the drilling detection system was developed, and achieved the real-time remote transmission of image and sound, gas parameters and other key information. The detection system could be used in searching on miners in distress, fault diagnosis of large diameter drilling hole, real-time and dynamic monitoring of environmental parameters in underground disaster area. This device was successfully applied in the rescue work of the mine dynamic disaster accident, which happened on Dec.25, 2015, the Yurong gypsum mine collapsed in Pingyi County, Shandong province, PR China.
