This paper proposes a method for creating a three-dimensional (above-ground and underground) fracture network in deep coalbed methane (CBM) reservoirs, which is the directional fracturing by slotted hydraulic blasting in underground drilling. First,

Let $ n $ be a positive integer with $ n > 1 $ and let $ a, b $ be fixed coprime positive integers with $ \min\{a, b\} > 2 $. In this paper, using the Baker method, we proved that, for any $ n $, if $ a > \max\{15064b, b^{3/2}\} $, then the equation

Let a , b , c be fixed coprime positive integers with min { a , b , c } > 1 . In this paper, combining the Gel'fond–Baker method with an elementary approach, we prove that if max { a , b , c } > 5 × 10 27 , then the equation a x + b y = c

Let $a,b,c$ be fixed coprime positive integers with $\min\{a,b,c\}>1$. In this paper, by analyzing the gap rule for solutions of the ternary purely exponential diophantine equation $a^x+b^y=c^z$, we prove that if $\max\{a,b,c\}\geq 10^{62}$, then the

Sandwich masonry wall, namely, multi-leaf masonry wall, is widely applied as energy-saving wall since the interlayer between the two outer leaves can act as insulation layer. New types of sandwich walls keep appearing in research and application, and
