The act of blowing something up or destroying it with dynamite; using dynamite.
From dynamite + -ing (present participle suffix). This gerund form became common in the 1870s-1880s as dynamite use spread in mining, construction, and—unfortunately—political violence.
The practice of 'dynamiting' for mining and construction literally shaped modern geography: tunnels through mountains, dams, canals—much of our infrastructure was carved out using this one explosive.
