The invention discloses an ultrasonic zoning excitation auxiliary rock breaking device which comprises a rock mass inherent frequency zoning detection system and an ultrasonic zoning excitation system, the ultrasonic zoning excitation auxiliary rock breaking device is installed on a rock drill through a cylindrical fastening propelling device, and a hydraulic propelling device ensures that a compaction sector ring is tightly attached to a rock mass; the rock mass inherent frequency partition detection system performs annular partition amplitude detection on the surface of a rock mass through a compaction sector ring, data is transmitted to an amplitude data collection system and an inherent frequency analyzer, and inherent frequencies of all partitions are determined and transmitted to an ultrasonic generator; high-frequency alternating currents with different frequencies are input into the ultrasonic generator, the high-frequency alternating currents are input into the ultrasonic transducers which are annularly arranged and mutually independent through the circuit control system according to the frequencies, and vibration generated by the ultrasonic transducers is concentrated to the compaction sector ring at the top end through the amplitude-change pole. And performing partition excitation of different frequencies on the construction rock mass. Therefore, large-range and high-efficiency excitation of the rock mass is realized.

The invention discloses an ultrasonic focusing type deep rock breaking auxiliary device and a dynamic excitation method thereof. The device comprises a fastening propelling device, a rock inherent frequency detection system and an ultrasonic focusing excitation system which are arranged outside a drilling machine in a sleeving manner. Wherein the ultrasonic focusing excitation system is used for converging ultrasonic energy into a rock mass in front of a drill bit through a plurality of focusing acoustic lenses which are annularly arranged and can independently rotate. During working, the inherent frequency of a rock mass is detected firstly, ultrasonic waves with the corresponding frequency are generated, then the refraction angle of the ultrasonic waves is adjusted by dynamically rotating the focusing acoustic lens, a focusing point is made to move forwards synchronously along with increase of the drilling depth, and continuous and accurate presplitting of deep rock in front of a drill rod is achieved. The rock strength can be effectively reduced, the rock breaking efficiency is improved, meanwhile, the hole wall completeness is protected, and drilling tool damage is reduced.

The invention discloses a method for preparing ceramsite by using tailings after iron extraction of red mud, which comprises the following steps: 1, separating elemental iron and tailings after iron extraction of red mud: after deep reduction of red mud, melting the red mud raw material at a high temperature of 1500-1700 DEG C, and separating liquid elemental iron and molten tailings; according to the method for preparing the ceramsite from the tailings obtained after iron extraction of the red mud, full-process resource utilization of the red mud from iron extraction to preparation of the ceramsite from the tailings is achieved, the traditional stacking or landfill treatment mode of the tailings obtained after iron extraction of the red mud is changed, a large number of land resources are saved, potential hazards to the environment are avoided, and the method is suitable for industrial production. According to the method, the tailings obtained after iron is extracted from the red mud are converted into ceramsite with economic value, so that the red mud is fully utilized, the pressure of solid waste on the environment is reduced, the comprehensive utilization rate of resources is improved, a benign resource circulation system is formed, and sustainable development is promoted.
