The invention discloses a throughput improving method based on a DAG structure block chain. The method comprises the following steps: electing a trusted consensus group; after a new transaction is generated, the transaction is sent to the credible consensus group for verification, and the credible consensus group verifies the validity of the transaction according to the actual assets and the expected assets of the two parties of the transaction and sends the transaction to the corresponding message queue; the nodes select transactions from the message queue according to own strategies, package the transactions and send back confirmation messages, and at the moment, the credible consensus group updates the database in real time according to the confirmation messages; then, the node packages the blocks by adopting a PoW algorithm under a DAG structure and issues legal blocks; and when one block is successfully published, the trusted consensus group verifies the transaction in the legal block, updates the message queue, removes the transaction from the normal message queue, and transfers the related blocked transaction from the blocked message queue to the normal message queue according to the Hash of the two transaction parties. According to the method, the repetition conflict rate of the transaction is optimized, the sequence conflict problem of the transaction is solved, and the throughput is improved.

The application provides a kind of ultrafine tailings cemented filling material slurry flocculation network formation time test method, and relates to the technical field of mine filling mining.The application prepares ultrafine tailings cemented filling material slurry and pure ultrafine tailings slurry body, uses dynamic rheometer to carry out strain amplitude test of fixed frequency, obtains the complement of linear viscoelastic region of two kinds of slurry body;Using dynamic rheometer, the frequency scanning test of fixed strain is carried out on the ultrafine tailings cemented filling material slurry, and the equilibrium frequency is obtained;Pre-shearing is carried out on the ultrafine tailings cemented filling material slurry, to ensure that all filling material slurries are in the same repeatable reference state;After the pre-shearing process, the time scanning test of fixed strain and frequency is directly carried out, to determine the flocculation network formation time of the ultrafine tailings cemented filling material slurry.The application helps to deeply understand the flocculation and sedimentation process of ultrafine tailings and the fluidity of ultrafine tailings cemented filling material slurry, so as to optimize the proportioning, and finally improve the utilization rate of ultrafine tailings.
