What are you even talking about? Nothing stops women from joining mining. As I already pointed out, according to the Mine Safety and Health Administration, "Today, women hold every type of job available in the mining industry, from general laborer to mining engineer in underground and surface mines, and coal metal and nonmetal mines."
"While not leaders of the pack, the mining sector (along with utilities and energy) does seem to attract women, with about 40 percent of entry-level roles being filled by women. So where does mining lose them?
Women report leaving—or wanting to leave—the industry because the qualities that originally attracted them to the field don’t anymore (Exhibit 3). The top reasons for leaving the industry are feeling that work is no longer intellectually challenging and having the perception that there are fewer advancement opportunities than there are for their male colleagues. Interviews with leading women in mining highlight that women experience being sidelined, particularly in technical roles. There is a sense that opportunities for operational experience and frontline mentorship are created proactively for men, while women are expected to have acquired frontline experience “elsewhere” in order to qualify for advanced technical and leadership roles. Women who return to school to further their expertise feel that their academic skills are underutilized and undervalued, negating their investment in advanced education. There is also a perception that operational experience is rated more highly than advanced qualifications when it comes to attaining advanced technical and leadership roles, but women struggle to access the same “stepping stone” operational roles as men do in the same organizations."
The fact that 40% of entry level roles are filled by women doesn't track with your "I've just decided how things must be" blather. You are highly invested in your narrative and don't seem to care much about the facts. It's pretty pathetic.
