Abstract: An undercut excavation method is provided, which is particularly suitable as an undercut-and-fill mining method, wherein concrete posts are inserted into holes drilled in the ground and are used to support a concrete floor poured on their top ends, which serves as a roof for the lower excavation level. The bottom ends of these posts rest on resilient elements to provide protection against seismic events or excessive ground movements. Excavation beneath such roof is thereby safely carried out in areas prone to seismic events such as rock bursts or earth quakes or to excessive ground movements. The concrete posts may be attached to the resilient elements at their bottom ends, thereby producing yielding posts suitable for such excavation. For still greater safety, a double post system may be used, which involves placing a second post beside the first after excavation on a given level and tying them all together with the concrete used to make the floor/roof for the next lower level of excavation. In mining this is called double-post mining or DPM.

Title: Secret communication and authentication scheme based on public key cryptosystem using n-adic expansion
Inventor: TAKAGI TSUYOSHI
IPC: H04L9/30
Filed: 1997-08-08
Granted: 2001-08-07
Abstract: A secret communication and authentication scheme based on a public key cryptosystem in which a decryption speed is improved while maintaining a security level. In the RSA type secret communication, a plaintext is expressed in a form of a k-digit n-adic number and a ciphertext is obtained by applying a calculation using the first public key n and the second public key e to the n-adic number and transmitted. Then, from the received ciphertext, a lowest digit of the n-adic number is decrypted by using the first public key n and the second secret key d, upper digits of the n-adic number are sequentially decrypted by using a decrypted value of the lowest digit of the n-adic number at the receiver side, and the plaintext is recovered by using decrypted values of respective digits of the n-adic number. The Rabin type secret communication can also be realized by the similar scheme. Moreover, the same principle of the n-adic pubic key cryptosystem can also be used in realizing the RSA type or the Rabin type Authentication.
